This article is for Netflix's first original animated series Bojack Horseman's character.

Played By: Paul F. Tompkins

"Mr. Peanutbutter and BoJack Horseman in the same room! What is this, a crossover episode?"

A native of the Labrador Peninsula in Canada, Mister Peanutbutter was raised in the countryside as the runt of the litter with his parents and grandma, free of the world's cold touch. Submerged in a saccharine and comfortable sugar bowl where the motto was "Nothing bad ever happens in the Labrador Peninsula", PB grew with the expectation the world was just as light. During a trip to Hollywood, he wandered off against his wife Katrina's objections and stumbled onto the set of Untitled Horsin' Around Ripoff. With his carisma and natural ability, Mister gained the public's favor, taking the role from Vincent D'Onofrio. Money and second rate fame ensued with the newcomer PB helming what henceforth would be called Mr. Peanutbutter's House.


Growing at the shade of the much more famous BoJack Horseman, PB quickly took to being famous, even if he preferred to be a good sport about it, contrasting BJ himself whom he gradually started idolizing and view as a peer in the industry, admiring his work even if he constantly failed to get most of the scorn thrown his way by the horse.

  • Aborted Arc: The first season plays up Mr. Peanutbutter's Bitch in Sheep's Clothing tendencies, implies there might be a sinister reason he was married twice before Diane, and when BoJack has a one-night stand in their bed, he hides a picture of Mr. Peanutbutter and Diane... only to reveal another picture of Mr. Peanutbutter in a mysterious other woman's arms behind that (that BoJack doesn't notice and hides too). Later seasons played up Mr. Peanutbutter being a Nice Guy, an Extreme Doormat to two bitchy ex-wives, and the mystery woman in the photo seems to have been dropped.
  • Acceptable Targets: In-Universe. BoJack practically makes him the butt of his many putdowns, since he believes he doesn't care or notices. Mr. Peanutbutter has always been kind enough to set the record straight when BoJack crosses a line that, no, he does notice and yes, it stings.
  • Adaptational Dumbass: In the documentary mentioned below, Mr. Peanutbutter's intelligence is downgraded (if that's even possible) even further than normal until the only thing he can say is "True Dat" over and over. Especially egregious since he was supposed to be the main character of the movie in the first cut, as revealed by the title.
  • Adaptational Intelligence: His fictional counterpart in Mr. Peanutbutter's Hollywoo Heist played by BoJack amps up the gift of speech as well as the form of expressing oneself in flowery metaphors regarding his relationship with Diane, contrasting with the real PB's more colloquial terms of approaching the subject with her.
  • Adaptational Personality Change: In-Universe. In the adaptation of "Mr. Peanutbutter's Hollywoo Heist", a documentary about Mr Peanutbutter getting married to Diane with Bojack as a minor character gets derailed into making Mr. Peanutbutter a Flat Character that spews a single catchphrase of dialogue over and over.
  • Adorkable: Mr. Peanutbutter is a lovable, derpy goofball, through and through.
  • Aesop Amnesia: Played for Laughs at first, Played for Drama later. Mr. Peanutbutter is somewhat aware of his shortcomings as a dog (he admits he's not the one who usually gets bored in a relationship) and a husband (he tries, but can't remember to make compromises for his wives). And it's not like he can't see he's running out of time to change. But he just can't get himself to admit it, let alone act to fix it. He's way too reckless, distracted, and reliant on good vibes to begin confronting his dark side. As he is, he's always been comfortable that way and expects everyone to be, even when people get tired or frustrated with him. Better to blame it on "not being able to change" or to move on quickly to the next thing, regardless of whether that's the healthiest thing to do.
  • Alcohol-Induced Idiocy: In between seasons, he got drunk and punched a mirror thinking that it was someone else using his same outfit, leading to a broken hand and the use of a cone. This causes him no end of grief since he has little to no peripheral vision on the sides and often confuses people.
  • All-Loving Hero: Deconstructed. He is fun-loving, friendly and has a positive and cheerful attitude. In this case, people who interact with him on a daily basis believe him to be a moron, or just get irritated with his behavior. He's also shown to mostly be nice because he wants other people to like him, even if it causes them no end of grief or frustration. (Like his grand romantic gestures for Diane making her uncomfortable, or his run for governor of California causing a huge unnecessary mess.)
  • Always Someone Better: He's this to Bojack, until he's revealed to be an Anti-Nihilist.
  • Ambiguously Bi: He is married to Diane and his previous marriages were also with women. He's also incredibly okay with the idea of kissing Bojack on the mouth. Almost to the point of eagerness. He's also rather casual about taking a nude tomato bath together with Todd.
  • Amicable Exes: He tries to be this with all of his ex-wives. Results are... mixed. This even includes Diane in Season 5 after their divorce papers are filed. It seems to be going okay at first despite some awkwardness, until she sees him kissing another girl at a party. Later deconstructed when their failure to set healthy boundaries leads to him cheating on his current girlfriend with Diane.
  • Animal Stereotypes:
    • Has a short attention span, gets excited when the doorbell's rung, and is very energetic and playful. He also hates the post office and mail carriers.
    • He also fits the "big friendly dog" stereotype; he's always excited to meet new people and tries to be Fun Personified. The keyword here being "tries." Mr. Peanutbutter's problem is that he can't seem to realize how grating this attitude can get. In his mind, everyone should be like him, because that's the only way to properly live.
  • The Anti-Nihilist: Mr. Peanutbutter seems to be an example of the trope at first glance: In his own words, life is largely miserable, and the best way to deal with that is to distract yourself from it as often as you can, enjoying every moment until you die. However, it's gradually subverted the more and more the series goes on; it becomes clear that for PB, this doesn't mean "accept your mortality and insignificance, and move on with the things that really matter." Rather, it means "deny anything that's wrong and focus on the exciting parts", which is just a more hedonistic form of nihilism itself.
  • Armor-Piercing Question: Mr. Peanutbutter delivers one to BoJack, asking him why he has always spit bile on his way and on everyone when he has everything he could want, after reaching his breaking point in "Let's Find Out". Mr. Peanutbutter gets an Armor-Piercing Response in return from Bojack. What Bojack wants, more than anything else, is to feel good about himself.
    Mr. Peanutbutter: Oh, and it doesn't [come easy] for you? You're a millionaire movie star with a girlfriend who loves you, acting in your dream movie. What more do you want? What else could the universe possibly owe you?!
  • Ascended Fanboy: As a child, he was a big fan of Hank Hippopopalous, getting his album The Hank Hippopopalous Hip-Hop Hypothesis and taking a picture of him and BoJack with good ol' Uncle Hankie at the Emmys. In 2015, Mr. Peanutbutter becomes Hank's co-worker when HSAC:WDTKDTKTLFO! and I Think You Can Dance are put back-to-back in MBN.
  • Awful Wedded Life: His first marriage was with an abusive woman named Katrina, who often humiliated, ignored and cheated on him. Quite openly, in fact. His second marriage with Jessica Biel wasn't all that much better. His marriage to Diane has devolved into this in season 4, and at the beginning of season 5 they get divorced.
    Mr. Peanutbutter: Okay, I gotta go. My wife's hand just disappeared into that busboy's pants. Treasure? Sweetheart? We're in public.
  • Bad Boss: When the women drivers of Cabacadabera complained of male customers making them uncomfortable due to sexual harassment, Mr. Peanutbutter had them fired and replaced with female whale strippers from Whale World.
  • Believing Their Own Lies: A psychologist could have a field day with him on this one.
    • He believes himself to be The Ace whose natural talent, charisma and good attitude earns him numerous gigs and scores in his business. Not only is he a complete covert cad with no idea of how to handle his PB Livin’ brand beyond obtaining rights for meaningless projects, funding asinine ideas and spending money without earning revenue; his idiocy and tactless behavior is what keeps him getting acting jobs since it’s fused with his fun-loving, clean side.
    • He picks up women who he thinks are just as free-thinking and cheerful as he is......ignoring the fact they’re way younger than him, making him a borderline Dirty Old Man, and his immaturity compared to them makes him the odd dog out when they outgrow and leave him. Furthermore, his assumption he just dates women with these features leaves him ignorant of his subconscious superficial nature by being unwilling to date someone his age.
    • He thinks he and BoJack are friends and he respects him very much. While this is just self-denial (he’s aware how much the horse despises him), it speaks volumes of his self-delusion that he’s kept this belief for more than 20 years.
    • He thinks believing in yourself and having a good disposition is all that's needed to be successful at life. Partly, yes, but this is only because that’s what has worked for him in a town like Hollywoo and he believes it's the same for everyone.
    • He insists he's a good boss even though he's willing to ignore their desires and needs if it inconveniences him.
    • In a more specific instance, in Season 1 he stole credit from BoJack for the Hollywoo Heist. By the next episode he seemed to genuinely believe he did it.
  • Belligerent Sexual Tension: While not a full blown brawl fest like others, his and Diana's relationship devolves into this as of season 4, mainly since their marriage has largely becomes sexless at this point and the frequent arguments each of them has with the other over issues they're diametrically opposite in disagreement, as well as the fact that Mr. Peanutbutter agrees with everything to keep the public support and is being guided by Katrina through hand in every step of the governatorial campaign. This is not portrayed as a good thing, however: if anything, it's done to portray how increasingly desperate both of them are to work things out and how increasingly they're running out of options.
  • Berserk Button:
    • As a dog, he hates mailmen.
    • He hates watching tennis because no one catches the ball.
  • Beware the Nice Ones: As BoJack finds out, that he's willing to put up with most of the insults he receives his way doesn't mean he doesn't have a tipping point and that when it reaches its peak, he is going to stand up for himself.
  • Beware the Silly Ones: As BoJack and Diane find out at different times, this ditzy dog will lose his silliness when he's pissed.
  • Big Brother Worship: Mr. Peanutbutter really looks up to his older brother, Captain Peanutbutter. Deconstructed in that it's Mr. Peanutbutter's idolizing of his brother that causes him not to ask Captain Peanutbutter if something is wrong.
  • Big Damn Heroes: During the Season 3 finale, though he could have arrived two hours earlier instead of the nick of time if he hadn't turned off his phone.
    • In a smaller yet no less important example, he's the first one to run onto the Philbert set in "The Showstopper" and pull BoJack out after he genuinely strangles Gina under the influence of drugs.
  • The Big Damn Kiss: With BoJack in "Let's Find Out".
  • Big, Friendly Dog: He's the friendliest and most cheerful character of the series.
  • Birds of a Feather: A platonic example with Todd — Both are ditzy, friendly men with a strange way of thinking.
  • Bitch in Sheep's Clothing: Comes off as very friendly early on. Once BoJack starts competing with him for Diane, his douchier side begins to emerge. This is hinted at in the first episode, when BoJack actually responds honestly to Mr. Peanutbutter's concerned-sounding "How are you?", cutting BoJack short with "Living the dream, huh?" and wandering off.
    • He also willingly steals BoJack's thunder on multiple occasions. He blows BoJack off when he spells out that he's not fond of him for starring in an obvious knock-off of his show. And when BoJack comes to him for help getting rid of the giant D from the Hollywood sign, Mr. Peanutbutter uses BoJack's trust to plant the sign in his front yard and steal credit for the grand romantic gesture.
    • While a genuine Nice Guy, Mr. Peanutbutter is pretty dense when it comes to women's issues, yet another issue in his marriage to Diane, an outspoken third-wave feminist. When Hank Hippopopolous is revealed to have sexually assaulted all eight of his former secretaries, Mr. Peanutbutter doesn't seem that bothered to learn his idol is a monster behind closed doors, doesn't support Diane when the public turns against her (something even Bojack does), and pressures her to give up opposing Hank because it's hurting his show... a show he later reveals he doesn't even really care about, since he later forgets to come to work when something more exciting came along. When he joins Todd's business venture in Cabacadabra, it's Mr. Peanutbutter who suggests firing female drivers who feel uncomfortable with male clients sexually harassing them and replacing them with Whale World strippers, and laughs off Diane pointing out that he turned Cabacadabra into yet another sexually exploitative business despite it being formed to be the exact opposite of such a thing. When Diane tries to empower women through female gun ownership and Straw Misogynists complain about not feeling safe anymore in such a manner that shows that they are clearly more threatened by women having weapons than by having people's lives in general be in danger, Mr. Peanutbutter runs a standard gun control platform as part of his campaign and treats Diane as if she were a radical NRA member who just likes guns too much, ignoring her genuine concerns about female safety in male society and her reasoning as to why a woman would want a gun in the first place.
    • Season 5, particularly "Mr. Peanutbutter Boos," explores this further, revealing that his outwardly fun-loving but internally selfish and inconsiderate idea of fun was part of the reason all his previous marriages fail. When he brought Katrina to a Halloween party, he constantly wandered off to have fun despite her constant begging not to be left alone, until she finally blew up at him. Jessica Biel... to his credit, he tried with that one. With Diane, he pressured her to go talk to BoJack despite her clear discomfort, then acted surprised when she returned in tears. He also subliminally pressured Diane to be "fun and cool" rather than mean and cynical like his previous wives despite constantly forgetting that she hates big parties and Grand Romantic Gestures, pressuring her not to act like a Wet Blanket Wife and accusing her of being ungrateful for all his thoughtful gestures, and putting a huge strain on and eventually ending their relationship. And then his constantly bringing up or talking about Diane near Pickles makes her feel insecure... until Mr. Peanutbutter cheated on Pickles with Diane.
  • Boke and Tsukkomi Routine: Every interaction Mr. Peanutbutter has with BoJack has shades of this, with BoJack playing the Tsukkomi (Straight Man) to Mr. Peanutbutter's Boke (stupid guy).
  • Book-Ends: Diane & Mr Peanutbutter's engagement/marriage begins & ends with Mr Peanutbutter making a grand romantic gesture that Diane ultimately doesn't feel comfortable accepting. Immediately after Mr Peanutbutter asks Diane to marry him with "just the two of them, no cameras" there is an immediately surprise party and a scene where Diane calls Bojack and is clearly not happy. It ends when Mr Peanutbutter recreates a childhood fantasy of Diane's without realising why it wasn't something he should have done and why Diane can't appreciate it.
  • Born Lucky: BoJack cites this as a reason why he can't stand him in "Let's Find Out". While BoJack's hatred of him borders on Irrational Hatred, he does have a point by saying that Mr. Peanutbutter gets everything he wants with little to no effort. He didn't even had to work his way up, he starred on a Captain Ersatz copy of Horsin' Around (which season 4 reveals he got by just happening to wander onto the set of "Untitled Horsin' Around Knockoff" and unintentionally charming the audience) and when in need of a job, he ends up with two options, one of which he never noticed! Ultimately, Played With however as it's implied that before starring on Mr. Peanutbutter's House, he was a Starving Artist who lived on the streets.
  • Break the Cutie: In season 2. Slowly starting to realize that your seemingly perfect life isn't set on stone, that you're getting old, that you can't change at the same pace as your romantic partner and that you're expendable in the eyes of your superiors will do that to you.
  • Brooding Boy, Gentle Girl: Mr. Peanutbutter's relationship with Diane is a Gender Flipped version of the trope: he is caring, quite lightheaded and simply soothes her worries while she is troubled, torn between cynicism and idealism and full of doubts while.
  • Butt-Monkey: To BoJack, who abuses and dismisses him at every turn. It's not with complete impunity, however. Mr. Peanutbutter does notice Bojack's barbs; he just tries to avoid confronting them.
  • Canada, Eh?: Downplayed. While he doesn't have a Canadian accent, he was born and raised in Labrador before becoming a celebrity.
  • Catchphrase:
    • "What is this, a Crossover?" in the earlier episodes. Even later, he still uses it from time to time especially with a special twist, "What's this, a Very Special Episode?", when he finds out his brother has a twisted spleen.
    • "True Dat" in the adaptation of "Mr. Peanutbutter's Hollywoo Heist", due to some small tweaks at the original idea.
  • Character Blog: After BoJack's disappearance after season 3, Mr. Peanutbutter takes notice of the fact that he left his Twitter account open in his computer, so naturally he starts writing joke posts (mostly about his complicated relationship with BoJack and desire to be his friend, claiming it's BoJack and Mr. Peanutbutter is his best friend, etc.). Once he sees that BoJack is not erasing any of the posts, he realizes he might be truly gone BUT on the other hand, he's running for governor and really needs a social account, so...
  • Character Development: Mr. Peanutbutter's underlying darker outlook becomes more apparent in Season 2.
  • Character Tics: As Princess Carolyn points out in "Let's Find Out", Mr. Peanutbutter's ears flop up when he is excited.
  • Character Title: Two In-Universe examples. The first appears in "BoJack Hates The Troops" when he makes a deal with VH1 to produce a reality show called "Peanutbutter And Jelly" and the second when he starsnote  in an adaptation of his actions called "Mr. Peanutbutter's Hollywoo Heist".
  • Chick Magnet: He was married twice to Katrina (first) and Jessica Biel (second) before divorcing them for different reasons. Sometime after his second divorce, he began a relationship with Diane that led to marriage. And in "Higher Love", while he worked as a lady shoes salesman, many women were excited to see him. His current girlfriend becomes attracted to him nearly instantly after they first meet while having dinner with Diane, his now ex-wife.
  • Cloud Cuckoolander: Especially considering his and Todd's business ideas like being all for opening a Halloween Store in January or making a mood that you can drink.
  • Comedic Sociopathy: With his new television show cancelled and his usual accomplices (Bojack, Todd, and Diane) otherwise occupied during Season 3, Mr. Peanutbutter decides to start anew. His first order of business? Kidnapping his accountant from his home and family.
  • Cone of Shame: Wears one in "Brand New Couch" due to drunkenly punching a mirror thinking it was another dog between seasons.
  • Cool Shades: They hang on his V-neck or on the top of his head. Strangely, he never uses them.
  • Cool Uncle: "Old Acquaintances" show he's a fun uncle to his big brother's children.
  • Crazy Jealous Guy: Downplayed. While Mr. Peanutbutter doesn't act or go "crazy", he does become more territorial when Bojack begins to show an interest in Diane or if Mr. Peanutbutter thinks another guy may flirt with Diane (i.e., one of his reasons for not wanting Diane to go to Cordavia is because he was afraid Sebastian St. Claire may do just that).
  • Crouching Moron, Hidden Badass: Peanutbutter has pulled off quite a few brave and heroic acts, such as:
  • The Danza: An In-Universe example; his TV character was also named Mr. Peanutbutter.
  • Dark and Troubled Past: Implied. He's made a couple of mentions of being a literal starving artist and then there were his marriages to his two emotionally abusive, unfaithful now ex-wives.
  • A Day in the Limelight: Mr. Peanutbutter has "Higher Love" and "Let's Find Out" in season 2; "Start Spreading The News", "The BoJack Horseman Show", "BoJack Kills", "Love And/Or Marriage", "Brrap Brrap Pew Pew", "Old Acquaintance" and "That Went Well" in season 3.
  • Dead Sparks: By the end of season 4, this is what his and Diane's marriage has devolved into. It says something neither is keen in entering their new house in "What Time Is It Right Now?" to continue living together or Diane just doesn't have the strength to keep putting the work in their marriage.
  • Dirty Coward: He eventually reveals himself as this in "The Stopped Show". Having received more than one wake up call about needing to change and come clean to Pickles over their incompatibility and his affair, he's unable to do so. This is both out of fear of breaking her heart, and his own fears of being alone and having nobody like him. So PB randomly proposes to Pickles instead, proving once and for all that he'd rather keep lying to avoid a bad situation rather than speaking the Awful Truth.
  • The Ditz: He's not that smart. Downplayed in that he's not really stupid either, just foolish and naive and more on the ball than people give him credit for. Also, it's deconstructed in that the great difference between his intellect and everyone else is a major source of angst and insecurity on his part.
  • Did You Think I Can't Feel?: He calls out Bojack on always insulting him to his face, despite the fact that PB has never been anything but nice to Bojack, and he has tried to become friends with him on more than one occasion. Mr. Peanutbutter makes it clear that he's fully aware about all of BoJack's insults, and yes, they do sting.
  • Dirty Old Man: The one thing that Mr. Peanutbutter sees in all women is their youth and carefree nature, which unfortunately predispones him to choosing very, very young women who are barely beginning to understand the world. He’s in deep denial over this and prefers to believe he just “ruins” them, but as the series goes on, this becomes a worsening problem for him with failed marriage after failed marriage due to his unaware jackass behavior, immaturity and lack of intelligence picking them apart and gradually going for younger girls, culminating with Pickles, his girlfriend in season 5, who is less than half his age. When Diane suggests one way to break his divorce cycle is to start dating older women (i.e. women his own age), he actually grimaces.
  • Divergent Character Evolution: Played for Drama. Mr. Peanutbutter starts the series in the same page and with the same attitude as Diane, never arguing and always been happy in each other's company. The more Mr. Peanutbutter is left behind due to his adherence to his old ways and the more Diane develops independence and individual goals in mind, the more and more they start arguing and drifting apart. Which is not to say they completely disagree in everything. Or have stopped loving each other. Just that...they might want different things and neither wants to give in completely. It's clear that the Character Development they're going through is good for both of them, even if there's the implication they're might not work together at all if they continue growing separately as people.
  • Does Not Like Guns: He admits to hating guns and even hates people making gun sounds.
  • The Dog Bites Back: During "Let's Find Out", he finally snaps at Bojack after he claims that Diane left L.A. to get away from her and Mr. Peanutbutter's "awful marriage" and proceeds to grill him on live television, revealing that he's fully aware of all the contempt and ridicule his sitcom rival throws his way.
  • Dog Stereotype: Mr. Peanutbutter is a Labrador Retriever, and is thus incredibly nice (if a bit dim and has his moments of being Innocently Insensitive), light hearted and he has a very short attention span. He also hates Tennis because he doesn't understand why no one catches the ball.
  • Dogs Are Dumb: He has the simple-minded, excitable personality you'd expect from a dog.
  • Dogs Love Fire Hydrants: He's got a fire hydrant fountain in front of his home.
  • Dueling Shows: In-universe, Mr. Peanutbutter's Mr. Peanutbutter's House vs. Bojack's Horsin' Around. BoJack never misses an opportunity to tell anyone he's with that Mr. Peanutbutter's show is a rip-off of his.
  • Dumbass Has a Point: While the "dumbass" part is downplayed at best, Mr. Peanutbutter has the occasional insight from time to time.
    • He calls out Diane for continuing with her campaign against Hank Hippopopalous after she promised she would drop it.
    • After BoJack makes a hurtful jab at his relationship with Diane, Mr. Peanutbutter finally gives BoJack a major "The Reason You Suck" Speech — explaining that all he wants is to be BoJack's friend, but all the horse does is needlessly insult him.
    • Season 3 has him give Diane a What the Hell, Hero? moment after she spent a night investigating with BoJack, but didn't call home once to tell Mr. Peanutbutter what she was up to. Naturally, he was rather worried. The look on Diane's face indicates she knows she deserved it.
  • Dumb Blond: He's a yellow lab. And while not completely stupid, he is very naive.
  • Entitled to Have You: Platonic (mostly) version to BoJack. While BoJack is needlessly mean and insulting to him, nevertheless Mr. Peanutbutter knows deep down that BoJack despises him, yet for over twenty years Mr. Peanutbutter has ignored this and pushed his one-sided friendship anyway. In "Let's Find Out," when BoJack admittedly goes too far with a hurtful jab about his relationship with Diane, Mr. Peanutbutter uses the biased crowd and live television to pressure BoJack into giving him an apology and his friendship against his will, rather than address why BoJack might not want to be his friend (and BoJack has openly stated why many times), or respect the horse's wishes and leave him alone. Mr. Peanutbutter wants to be BoJack's friend, therefore BoJack owes him his friendship. (Though "Let's Find Out" implies it may not even be entirely platonic on Mr. Peanutbutter's end either.)
  • Establishing Character Moment: Mr. Peanutbutter doesn't have many appearances in the first episode, but enough to get shades of his character: He interrupts BoJack and Princess Carolyn's breakup by saluting them and then, trying to bond with BoJack and failing because of the latter's despise of the former, while remaining a friendly figure. Then, we find out that he starred in a similar Sitcom at the same time and with the same premise as BoJack, despite looking younger. There's also his dismissal of BoJack's brief moment of honesty during a party, which hints that there may be more to him than it seems. And he's Diane's boyfriend. Talk about Opposites Attract.
  • Fallen-on-Hard-Times Job: After going broke, he gets a job at a Lady's Footlocker. He enjoys it, though. However, he soon ends up as the host of J.D. Salinger's game show.
  • Fanboy:
  • Fatal Flaw: Mr. Peanutbutter has two flaws: Ignorance and Need To Be Loved.
    • Many of his personal problems with others are the direct result of his own actions. During Season 3 and 4, the earlier hints of his selfish behavior become much more apparent, and there are many times he outright rejects the advice of his wife or others in order to serve his own interests. There are many hints throughout season 4 that he's actually using Obfuscating Stupidity for the purpose of making himself look good, such as his replication of Diane's "Belleroom" as a move to try to make himself look like a caring husband, when in reality it's the exact opposite of what Diane really wanted.
    • His insecurity to be liked by others. This particularly comes into play where Season 4 where even Mr. Peanutbutter acknowledges he has this problem when he said this is why he wanted to run for Governor of California. In Season 5, he starts dating a adorable pug named Pickles whose personality seems similar to his so they get along. He still has feelings for Diane and has an affair with her near the end. He wants to come out and be honest with Pickles. He doesn't want to hurt her feelings and be hated by her that rather than tell her the truth......he randomly proposes to her.
  • Fat and Skinny: The slim, short, fit and much more well adjusted Skinny to the pudgy, tall, curmudgeon and reclusive BoJack's Fat, for a sense of fat.
  • Feeling Oppressed by Their Existence: Downplayed. PB's sense of blind optimism can withstand BoJack's cynicism, but only for so long before the cracks in his façade start showing and he thinks of all of his problems and flaws. As such, PB's tactic when interacting with BJ is to change subject, go away or angrily reject any change to his reality. Surprisingly, when both drop their defenses, they can get along quite easily.
  • Feigning Intelligence: Not very good at it, mind you, but he reveals in "Planned Obsolescence" he gave it a shot when dating Diane to compensate his trash pop-culture knowledge.
    Now I can say I’ve never seen The Wire and I don’t plan on doing so!
  • Female Feline, Male Mutt: The Male Mutt to Princess Carolyn's Female Feline.
  • The Finicky One: Heavily INVERTED. Unlike BoJack, Diane, Princess Carolyn or even Todd, Mr. Peanutbutter is perfectly happy to receive any kind of offer, never turning one down regardless of its pieceameal payment, ridiculous conception or even if it's foolish to do so. Be the presentation for John Edwards, the writing of an article for Buzzfeed, being proposed something by Michael Vick or simply being the face for Seahorse Milk, he's the kind of guy who will do anything if it pays or piques his interest.
  • Finishing Each Other's Sentences: He tries (and fails) to invoke this with BoJack.
  • Foil: To Bojack, since they both had a hit sitcom in the 80s, but while Bojack is bitter, antisocial, and depressed, Mr. Peanuttbutter is friendly, positive, and upbeat. However, the two are actually Not So Different. See Anti-Nihilist and Bitch in Sheep's Clothing above.
  • A Fool and His New Money Are Soon Parted: He has been declared bankrupt by his accountant, due to spending money on stupid ideas.
  • Freudian Excuse: Having wives like Katrina and Jessica Biel makes the subsequent manipulations Mr. Peanutbutter does to Diane to avoid losing her all the more understandable. After all, when you have had a crappy love life and you find someone as amazing as her, you'll want to hold onto her as long as you can.
    • Subverted in "Mr. Peanutbutter Boos," which reveals that Katrina and Jessica Biel used to be fun and carefree too, until they eventually outgrew his Manchild antics, and furthermore lost patience with his Innocently Insensitive at best (Bitch in Sheep's Clothing at worst) treatment of them. His fear of losing Diane too stems from his failure to recognize this pattern and he is unwittingly trying to prevent her from outgrowing him.
  • Friendly Enemy: To Bojack, though the friendly part of this trope often overpowers the enemy aspect. Hell, he actually wishes they could be friends. By season 4, they could be considered Vitriolic Best Buds in-training.
  • Full-Name Basis: "Mister" is his first name and "Peanutbutter" is his last name. Everyone refers to him as "Mr. Peanutbutter", except for the children of his brother, who call him "Uncle Mister".
  • Furry Reminder: He tends to get more of these than the other animal characters on the main cast and in a more overt way, probably because dogs are funny. For example, he hates baths, vacuums, and thunderstorms, owns a mug that says "Good Boy", sleeps in a giant dog bed, and enjoys rolling around on the lawn. He also distrusts mailmen, hates watching tennis since no one ever catches the ball, gets into a fight with the neighborhood skunk, gets skunked, rubs the stink all over the house trying to rub it off, and when he's wet with tomato juice he can't control the urge to shake it off.
  • The Generation Gap: Deconstructed in his marriage, starting in season 2. Diane is 35 years and Mr. Peanutbutter is pushing beyond 50. Despite working constantly to make their relationship work and mostly succeeding, it's clear that their life agendas couldn't be more different: Mr. Peanutbutter, despite his energy and niceness, is an Old Dog, way too accustomed to his ways and not that willing to challenge beyond what he has. Diane, on the other hand, is 35 and still has the opportunity (and desire) to allow herself onto wonders, experimentations, and experiences before settling into a permanent commitment, but because of her love towards Mr. Peanutbutter and how stable and loving their marriage is, it's hard for her to completely give in to what she wants, which causes further friction between the two of them. His current girlfriend is 25, and Mr. Peanutbutter sometimes struggles to relate to her.
  • The Ghost: Not Mr. Peanutbutter himself, obviously. But his good friend Erica, whom he often greets at parties and public gatherings, is always just off-screen.
  • Goofy Print Underwear: In the episode "Bojack Kills", it is revealed that he wears red boxer-briefs with hotdogs printed on them.
  • Graceful in Their Element: It's a given that were he not to live in Hollywoo where he's given a pass for his many mishaps, get a job without much effort and appreciated for his showmanship skills, PB would have starved to death several years ago.
  • Grand Romantic Gesture: He's big on these, which causes some conflict with Diane. Another one of these basically signals the end of their relationship.

  • Hair of Gold, Heart of Gold: Mr. Peanutbutter is a golden labrador and is a Nice Guy. (Mostly.)
  • Happily Married: Deconstructed with Diane. "Happily" doesn't translate to "totally functional". By season 3, their marriage has become so strained that the "happily" part is questionable at times. Then, in season 4 it seems they still have some opportunity to be together only for their personal issues and building resentment to break the camel's back, making both the "happily" and "married" not forthcoming choices.
  • Happiness In Minimum Wage: Out of the many jobs that fall into his lap in season 2, he takes the one with the lowest payment in his career: Lady Footwear as a clerk. Surprisingly, he’s content there doing his own thing and attracting people by juggling shoe boxes and dishing out compliments. This only reinforces what he likes the most: attention. It also shows what he lacks: foresight (if Princess Carolyn hadn’t seen him, it’s unlikely he and Diane would have been able to maintain their lifestyle, something that hadn’t quite dawned on him).
  • Has a Type: Like BoJack, he appears to have a preference for driven and intelligent women. Unlike BoJack, he's the one often left in a lurch by said women when they either get bored of him or start to recognize how large the gaps in their intellects are. "Mr. Peanutbutter Boos" further reveals that he's drawn to "fun and care-free" twenty-something women, but since he's still mentally in his twenties they inevitably outgrow him.
  • Henpecked Husband: To one of his previous, and much crueler, wives, Katrina.
  • Heroic Build: Despite his older age, he is pretty fit and muscular. As for the "heroic" part, he is one of the nicer characters on the show and can do heroic acts if the situation calls for it.
  • Heroic Dog: He's much more heroic than most people give him credit for. As of the third season, he's saved Todd from a burning roller coaster, saved Bojack from drowning and saved an entire underwater city with spaghetti strainers.
  • Hoist by His Own Petard: Dating Pickles makes him realize he’s getting too old to keep up with her youth and upbeat attitude, but he’s still too immature and fearful of change to move forward. In other words, he’s stuck.
  • Homoerotic Subtext: With BoJack and Todd.
  • Homosocial Heterosexuality: Most of the interactions and fights Mr. Peanutbutter has with BoJack over Diane are done with only them in the knowledge of what's going on. She's not present in most of their fights and wasn't even aware of both of their emotions until BoJack kissed her. The more details are given, it seems less like a fight over a girl and more like a battle of egos. It's taken even further when in "Let's Find Out", Mr. Peanutbutter and BoJack get into a heated discussion sparkled by Diane's mention that slowly drifts to a discussion about their...."complicated" relationship.
  • Hourglass Plot: His fortunes are inversely tied to Bojack's in season 2. As filming of Secretariat goes on and Bojack pursues his relationship with Wanda, Mr. Peanutbutter learns that Diane reveals that she's unhappy with their marriage and goes overseas to pursue "important" writing, PB Living goes bankrupt, Todd drifts away from him, his agent accidentally kills himself, and when it looks like he's bounced back into a lucrative television role, he finds out that the program has a lot of oversight from the higher-ups who make it clear to him that he is very expendable if he doesn't tow the line. Their attitudes are similarly contrasted with Bojack becoming more anxious and insecure in his newfound station and Mr. Peanutbutter trying to keep a positive outlook amidst all his setbacks. All this comes to a head during "Let's Find Out".
  • A House Divided: Increasingly as the series goes on:
    • The first major one was about Diane's desire to go to Cordovia to work with Sebastian St. Claire which was postponed at Mr. Peanutbutter's urgence in "Later".
    • Then, a fight breaks out in "After The Party" when Diane explodes over Mr. Peanutbutter needling her on facts and decisions about what she knows and wants.
    • During Diane's battle against Hank, she tries to get Mr. Peanutbutter's support on the subject, but Mr. Peanutbutter, in order to keep his job, is forced to side with the network and tries to dissuade her from continuing. Their diverging ideas and agendas only further the wedge between them.
    • The lack of communication between them, Diane's inability to express her feelings and Mr. Peanutbutter's pushiness masked in a cheerful façade in "Love And/Or Marriage" are also big factors in the somewhat stagnated process of couple's therapy. Once Diane takes some Gush, she expresses herself more openly mending the damage.
    • While staying in the Labrador Peninsula, Diane notices something is troubling Captain Peanutbutter, PB's brother. When she tries telling him, he dismisses her worries turning angry and even insulting her when she keeps insisting on the subject.
  • Idiot Houdini: A constant Decon-Recon Switch. Being good-natured may win him some points, but PB is one destructive idiot. Among his bad deeds include being unwittingly overbearing at every turn, dumb and inconsiderate enough to ditch most of the people he encounters even if it's rude to do so, performing genuinely life and career-threatening actions without a second thought in a daily basis, to the point where he's had to be bailed by other people when one of his schemes backfire. He's yet to be fully punished by it and most of his friends agree it's hard getting mad at him, since he's foolish enough to not know any better. Of course, while his gigs never flounder, his personal life has suffered because of it: now, when people just think you're a big joke and barely put up with you in a serious fashion, you know there's something wrong.
  • Iconic Outfit: Crossed with Limited Wardrobe, but his sole complaint about Bojack's portrayal of him in The Movie? That he's wearing a crew-neck t-shirt.
    Mr. Peanutbutter: I find it really troubling that my movie self is wearing a crew-neck T-shirt. [laughs] I only wear V-necks. You see the problem.
  • Ignored Epiphany: In "Mr. Peanutbutter's Boos," Diane has to spell out for Mr. Peanutbutter that his marriages keep failing because he's mentally still and keeps dating women only in their twenties, who inevitably mentally outgrow him. She tells him he can start dating older women, or grow up himself. He does consider the latter, but ultimately opts to keep having frivolous fun. At the end of Season 5, Mr. Peanutbutter again avoids dealing with relationship problems in a healthy and mature manner, instead cheating on Pickles with Diane and then just proposing to Pickles to gloss over their relationship flaws (like he did with Diane in Season 1), showing he's making the same mistakes that led to his three previous failed marriages.
  • Indy Ploy: When Bojack and Mr. Peanutbutter are discussing ways to get rid of the "D" laying in the former's pool, a trigger word gives the latter the idea of stealing the credit of the deed while he is lifting the letter sign and pretending to return it to its proper place.
  • Innocently Insensitive: While he means well, some of his actions to help others causes more problems than good.
    • Actually Deconstructed in Season 5's "Mr. Peanutbutter's Boos," which shows that the even though he's well-meaning or unintentionally doing it, the "innocent" part doesn't cancel out the insensitive part; and that consistently failing to notice or learn that certain behaviors come across as callous or insensitive to other people can wear away at their patience.
  • Insecure Love Interest: Towards Diane. For all of his happy-go-lucky, devil-may-care antics and the way he takes even the most distressing things at face value, he's revealed to be very afraid of losing Diane either by death or her leaving him.
  • Interspecies Romance: He (a dog) is married to Diane (a human). Both of his previous wives were also humans. Averted in season 5, where he's divorced Diane and goes on to date Pickles, who's also a dog (though she's a different breed from him, being a pug).
  • In Touch with His Feminine Side: He's emotional, open about his feelings, and preferred to wear a sparkly, bright pink suit during his time as a host.
  • It Runs in the Family: His brother and grandmother share his tendency of hiding their insecurities and sadness behind ever-happy facades.
  • It's All About Me: In a more subtle way than BoJack. While he's certainly more friendly and forgiving than BoJack in some aspects, he's revealed to have just as much as a deep rooted sense of inferiority which leads him to try to hang on the things that matter to him the most, often by trying to provide the necessary things for everybody to be content and fulfilled with their lives as long as they stay with him. He can be altruistic, but only when every other option has been taken away.
    • Diane calls him out on this in a Season 2 episode "After The Party" when he throws her a surprise birthday party, even though she's told him countless times that she hates parties. When Mr. Peanutbutter starts to retort that he assumed she'd love it, Diane retorts that that's his problem: Mr. Peanutbutter always assumes everyone is going to love something just because he loves it, without taking into account their own preferences. Mr. Peanutbutter then goes on a long, sarcastic rant about all the hard work he put into the party for her.
    • Comes to a brutal conclusion in the finale of season 4. He gives Diane a Grand Romantic Gesture gift and when she (once again) tells him she's not a fan of grand gestures, Peanutbutter basically blames it all on her and makes it about his feelings and abandonment issues, rather than acknowledging the fact that he rarely, if ever, listens to her. Their marriage ends as a result.
    • There are also shades of this in his many ideological conflicts with Diane. After he co-signs on a trivia show with Hank Hippopopolous and Diane unwittingly outs his sexual crimes against his secretaries to the public and the public turns on her as a result, Mr. Peanutbutter pressures her to give up on her crusade against Hank, not because she can't win and doing so would make her miserable (as BoJack points out, before agreeing to support her), but because doing so would hurt his career on the show... a show he later reveals he doesn't really care that much about, and often simply forgets to show up to work for. During Season 4, Mr. Peanutbutter also runs to be governor of California, not because he wants to help, but because he wants people to like him. Diane pointing out all the damage his frivolous campaign causes the state over the season falls on deaf ears.
    • Season 5's "Mr. Peanutbutter's Boos" explores this further. During all three of his marriages he would a) throw Halloween parties at BoJack's house that BoJack consistently didn't want (and vocally told him so), b) would drag along the woman he was seeing at the time and then promptly ignore her needs to have his own idea of fun, and consistently not listening when they try to tell him what an awful time they're having (like leaving Katrina alone for hours at a time despite her consistently begging him not to leave her in a room full of strangers, or insisting Diane go talk to BoJack so he can go do something fun), which would cause them all to become bitter and impatient with him by the end of the night.
  • I Just Want to Be Loved: Deconstructed. Mr. Peanutbutter's goal is to simply be loved by who he is. Unfortunately, he believes everybody should accept him as he is even after seeing how Be Yourself doesn't work when it screws up and messes with other people. He also has a tenuous grasp about love: namely, that it involves physical affection rather than mutual understanding.
  • I Want My Beloved to Be Happy: Deconstructed as he wants the people he loves to be happy his way, but when that doesn't work, he'll reluctantly do what he can to bring them joy in spite of himself. And when that doesn't work, it often leads to situations that could've been fixed if he talked it through with them rather than just superficially giving them gifts.
  • Japandering: Starred in a successful ad campaign for seahorse milk which ran in the Pacific Ocean.
  • Jerkass Ball: During season 2's "After the Party" and "Let's Find Out", he lets his fears and frustrations get the better of him and lashes out at the objects of his ire in the nicest and most venomous way possible.
  • Love Cannot Overcome: As much as they've tried over the first 3 seasons and even with a few Hope Spots in season 4, Diane and Mr. Peanutbutter have in his words "become roommates" rather than wife and husband. Despite their attempts in the season 4 finale and love for each other, they finally explode toward each other and their situation at the end indicates they know what's about to come.
  • Love Martyr: To Bojack, platonically, and to Diane, in a romantic sense.
    • He is also revealed to have been this to his two previous wives, which led to divorce.
  • Love Triangle: Between Mr. Peanutbutter, Diane and BoJack, especially in Season 1. Downplayed in Season 2, at least until "Let's Find Out."
  • Mailman vs. Dog: Mr. Peanutbutter has a problem with chasing the mail truck with his car. In "Horse Majeure" he gets pulled over for doing this and later loses his license. Even just mentioning the post office makes him growl.
    Diane: Were you chasing the mailman again?
    Mr. Peanutbutter: Yes, why? Did you see him out there too!? Nothing stops them! Not rain, not sleet, not dead of night, not gates!
  • Manchild: Obviously he has the mindset of a child; his solution to anything depressing in his life is to seek out simple pleasures. Once when he threw a surprise birthday party for Diane, he bought or rented many expensive and unnecessary things, including a ball pit. Addressed in "Mr. Peanutbutter's Boos" when Diane explains that Mr. Peanutbutter is mentally still in his 20s, so he keeps dating women who inevitably outgrow him.
  • Maniac Tongue: He is often seen flashing his tongue or just leaving it hang. Justified since, well, he's a dog.
  • Mean Character, Nice Actor: While he mostly plays characters that are just as nice as him, in Season 5, he ends up playing Fritz, a mean cop who isn't afraid to kill. He tries to toughen up his image in "BoJack the Feminist" but ends up failing miserably.
  • Meet Cute: Twice with Diane.
    • The first time was at a Starbucks when he and his second wife Jessica Biel go for a coffee. Diane is going for the fake name "Blarg", something that Mr. Peanutbutter takes seriously causing her to laugh.
    • The second was visiting him backstage after he had broken up with Jessica and they both talk. Diane finds it refreshing that Mr. Peanutbutter pays attention to her opinions and desires without mocking them, and he finds it great how nonjudgmental she is about his quirks and dim nature. Then, Mr. Peanutbutter takes off his shirt to the delight of Diane. From then on it's all history.
  • Mister Strangenoun: Mr. Peanutbutter.
  • Mortality Phobia: Peanutbutter is deeply afraid of his own inevitable death, and seeks out whatever he can do in life to distract himself and (pretend to) be happy.
  • Mr. Fanservice: As shown in a brief moment in the season 3 Whole Episode Flashback, "The Bojack Horseman Show", Mr. Peanutbutter has a pretty solid physique with pecs and muscle despite being in his middle age. Diane has a bit too much fun looking at his chest..
  • Narcissist: Contrasting BoJack, Mr. Peanutbutter overall fits the criteria for the "shy, covert narcissist" type mixing it with "compensatory": for all his supposed altruism and likability, he often shows to sometimes disregard what other people want in favor of what he thinks is the best way to make them happy, willing to accommodate everyone around him to ensure that they stay close and don't leave him. He also has a grandiose sense of projects, throwing the money away without concern for the future as long as the vision he has which is often of borderline ridiculous proportions becomes a reality and can often be really insensitive by ignorance or sometimes on purpose just to screw around. Rounding this is his insecurity when it comes to Diane, especially his fear of losing her or her finding someone better than him, which makes him be super devoted to her in an almost sickening fashion. Being a mixture of these types makes Mr. Peanutbutter be a dreamer of impossible proportions while at the same time a crowd pleasing actor with starving affection and huge neediness whose inferiority cause him to hide it.
  • Never My Fault: A cheerful and carefree version, but still. Another wacky business venture fell apart? Who could have seen that coming! Ah well, can't argue with Lady Fate. Guess it just wasn't meant to be. Now time to wander aimlessly till the next big opportunity presents itself and throw extravagant amounts of money at it till it too fails.
    • He also has this attitude to some extent to his failed marriages. Katrina, Jessica Biel, and Diane all used to be fun and sweet, but now they're mean and cynical. Who could have seen that coming? And Diane didn't appreciate all the fun parties or grand romantic gestures Mr Peanutbutter did for her. (Never mind all the times she's said she hates these.) Later Averted in "Mr. Peanutbutter's Boos," when Mr. Peanutbutter finally starts to realize he's the common denominator in all his failed marriages, and his tendency not to listen (and to not grow up despite choosing very young women who inevitably outgrow him) means he plays a part in his failed marriages.
  • Nice Guy: He is a good boy. Unless you're Bojack or a mailman, he's incredibly sweet and loyal. Matter of fact, he's quite nice and craves for BoJack's friendship despite his clear disgust at the dog. Deconstructed in more than one way: because he's so nice, some people believe him to be an idiot or a naïvely idealistic moron; his sense of optimism and good nature blinds him to any possible downfall in his plans and his life and he's not completely altruistic when cheering up people as he often does it as an way to feel better about himself. To cap it off, Mr. Peanutbutter's desire for other people to be happy can only fit insofar as how he thinks they could be happy without taking other opinions.
  • Not So Different: From BoJack.

  • Obfuscating Stupidity:
    • It's implied that he's not quite as brainless and naive as he lets on, but for the sake of others he plays the role. Particularly in the season 2 finale.
    • Princess Carolyn reveals that this is how he wins at poker, lulling his opponents into a false sense of security with his apparent bumbling.
  • Oblivious Guilt Slinging: Played with during season 2. His offhanded comments to Diane about how he loves spending time with her were calculated efforts to subtly push her into not going overseas. This continues after she leaves (and comes back) and he frequently calls her to tell her how proud he is of her humanitarian efforts, which are genuinely oblivious and do guilt-trip her since she's at Bojack's house.
  • Odd Couple: With Diane. She's intelligent, cynical and somewhat concerned about ideals. He's ditzy, optimistic (somewhat) and an Anti-Nihilist. While they love each other, the show doesn't pull away from showing how their stark differences often lead them into conflict.
  • Old Dog: Played with. He's still physically active and energetic, but he's also very set in his ways, and is unable to change his personality and life philosophy - he can't learn new tricks. This leads to conflict with Diane, as she wants to change and try new things, which makes him scared. He even calls himself this during a fight with Diane.
  • Older Than He Looks: It's easy to forget that Mr. Peanutbutter is supposed to be in his 50's by now just like Bojack.
  • O.O.C. Is Serious Business: Anytime Mr. Peanutbutter drops his usual energetic, friendly nature means that something incredibly serious has happened to make him more serious than usual.
  • Opposed Mentors: Along with Opposing Combat Philosophies, BoJack and Mr. Peanutbutter also have different approaches toward life that affect Diane one way or the other, with Mr. Peanutbutter embracing the inherent pointlessness of it and doing everything with the most energy possible; and BoJack looking long and deep at the despair and darkness of it all, including himself and taking full swings to the bottle of poison known as "cynicism", "logic" and "misanthropy".
  • Opposing Combat Philosophies: As part of their Foil status, BoJack and Mr. Peanutbutter have this. They're both former sitcom stars from the 90s, but while Mr. Peanutbutter faces the challenge with distractions and half-full methods, BoJack somewhat grasps and confronts the truth of the situation, realizing his past mistakes in the more harsher ways possible.
  • Opposites Attract: It's hard to say exactly what made Mr. Peanutbutter meet and fall in love with Diane, but they did and in an odd way, they do compliment each other. That being said, they may be slowly developing divergent agendas.
    • Deconstructed as the series wears on. Over time, their conflicting interests, desires, values, goals, and personalities create more and more of a strain on their relationship. Their increasing inability to reconcile their differences lead to bigger problems, huger fights, and greater compromises needed to keep their relationship together—which just leads to more friction and resentment on both sides. By the end of Season 4, Diane reveals that she can no longer take the never-ending stress of constantly having to reconcile their differences, signalling that their marriage is probably close to over.
  • The Other Marty: In-universe. Mr. Peanutbutter was cast in his sitcom after wandering on the set while the original lead, Vincent D'Onofrio, was filming the first episode. D'Onofrio quit the production, and Mr. Peanutbutter was hired on the spot.
  • Perpetual Smiler: It's hard to see Mr. Peanutbutter with a frown on his face. This is shown to be both a good and bad thing.
  • Playing Against Type: In-Universe. His role as "Fritz" in Philbert is miles from his lovable persona, which he lampshades by saying it's the "hardest he's ever acted". His girlfriend Pickles fails to understand he's just acting, switching between loving his real self and hating his character.
  • Pointy-Haired Boss: Much to the grief of his accountant, whose sound financial advice and warnings of his frivolous spending habits Mr. Peanutbutter ignores.
  • Poor Man's Substitute: Part of the animosity Bojack has for him is that Mr. Peanutbutter tended to mirror Bojack's career and choice of projects, particularly how "Mr. Peanutbutter's House" was an even more vapid knockoff of "Horsin' Around."
  • Professional Gambler: According to a flashback in "Let's Find Out", Mr. Peanutbutter used to go to "weekly how-do-you-do"s and clean the house with master poker skills around the Turn of the Millennium. Beyond the ''Mr. Peanutbutter's House" royalties, it was a welcome revenue.
  • Reading the Stage Directions Out Loud: A variant, with the Running Gag of whoever Diane or Mr. Peanutbutter hire for lettering.
  • Reality Ensues:
    • Played for Laughs with his crazy business schemes with Todd, which eventually result in him losing all his money and his accountant quitting due to the stress. That said, since Mr. Peanutbutter is Born Lucky, he quickly finds new roles and schemes that make him money again.
    • Very much Played for Drama regarding his hasty engagement to and marriage with Diane. In the first season, his resolution to the growing tension in their relationship due to their unspoken Love Triangle with BoJack is to propose. As more tensions arise during their planned year-long engagement, they choose to deal with it by shortening the engagement again and again, until they practically elope. The next three seasons show how marriage does not fix existing relationship problems, but actually exacerbates the problems they already had while dating (their different ideals, conflicting goals in life, Mr. Peanutbutter's jealousy over Diane's closeness with BoJack, Diane growing steadily more impatient with Mr. Peanutbutter's endless parties and Grand Romantic Gestures, etc) until they finally blow up at each other at the end of Season 4. By the time Season 5 rolls around, they're in the process of finalizing a divorce.
    • "Mr. Peanutbutter's Boos" highlights that being an Innocently Insensitive Manchild who dates only 20-year-olds well into his fifties causes his casual, fun-loving girlfriends to not only grow cynical and impatient with his selfish, childish antics in the long run, but they also inevitably outgrow him as they mentally mature while he doesn't.
  • Released to Elsewhere: Black Comedy example. He's unaware that his parents are dead because his siblings told him his parents were sent to a "farm" where they can run all they want... that also has no phone, internet, or mail. Because Mr. Peanutbutter lives on the border of Too Dumb to Live, he has to go through this at least twice: It is only days after confronting his mother's death that he realizes his father isn't "living on the farm" either.
  • Repeat After Me: In a Running Gag, when a banner appears, it usually has some instructions that the printer has idiotically left in.
    • Mr. Peanutbutter's frustration with the printing company is indicated on the shirts he orders for Diane's birthday
  • Riches to Rags: In season 2. Doesn't last long, though.
  • Rich Idiot with No Day Job: In season 1, when he spends most of his time just investing or creating outlandish ideas for products or reality TV shows. Not so much in season 2.
  • Running Gag: Often cuts off BoJack while greeting him at some social function to enthusiastically greet Erica, who's always standing somewhere off-screen.
    Mr. Peanutbutter: Erica! How are you? [insert some related nicety]
  • The Runt at the End: As pointed out by his older brother, he was the "little runt of the litter", yet beat the odds and rose to stardom.
  • Sad Clown: Heavily implied to be one, given his abusive ex-wives and unstable relationship with Diane. His nihilistic attitude of "distract yourself with happy stuff and don't think about bad things" also paints him this way.
  • Sealed with a Kiss: Non romantic example... probably. He mends up with Bojack this way.
  • Second Love: To Diane. Before meeting him, she was in a relationship with Wayne for some time.
  • Serial Spouse: His marriage to Diane in the first season was his third marriage. His exes show up on occasion, indicating they did not end amicably. By the fifth season it is examined further, in that he had something of a Manchild personality and he tended to marry young women, he remained perpetually young and energetic while they ended up maturing and growing too old for that behavior.
  • Sexless Marriage: By season 4, it's revealed that this is what his marriage with Diane has become. In "Commence Fracking," they try to have sex but quit when Mr Peanutbutter can't perform. Though it gets complicated by his political campaigning, as their political arguments — and, as revealed after their divorce, any type of argument — re-ignite their sex life. However, after the governor's business is said and done, their romance continues to die down until their eventual divorce.
  • Sheep in Sheep's Clothing: For the most part.
  • Smarter Than You Look: Mr. Peanutbutter might actually be more self aware than most characters. He can be somewhat ignorant at times but he actually is aware than not everything is great. He is aware than Bo Jack treats him like a big joke and yet he really does want him to feel good about himself. He really wants to be his friend.
  • Stalker Without a Crush: Diane offhandedly reveals that Mr. Peanutbutter often waits calls of BoJack, and goes berserk whenever Diane handles the phone, arguing that BoJack might be trying to call him right now. As a person, he's also relentless in trying to earn BoJack's friendship. Given what happens in "Let's Find Out", it may not be entirely platonic.
  • Static Character: In the first season, a handful of words could describe Mr. Peanutbutter's personality, namely "cheerful," "lucky," and "unobservant." It's later Played for Drama and Deconstructed. That is, while he has Hidden Depths and his situation changes from time to time, he avoids change altogether. He eventually reveals to BoJack that he believes nothing matters and so why be depressed when it doesn't matter what happens. In the fifth season, Diane explains to him that this is the reason all of his marriages fail. He stays the same but his wives inevitably grow up.
  • Stepford Smiler: It's heavily implied that his perpetually optimistic and cheerful attitude is merely a mask to cover up his nihilistic worries about life ultimately being cruel and meaningless.
  • Strange Minds Think Alike: With Todd. This eventually leads them to forming PB Living and pitch ridiculous ideas together, at least until the company goes under.
  • Taking the Heat: For BoJack stealing the "D" from the Hollywood sign. Or did he?
  • The Three Faces of Adam: Heavily played with; Mr. Peanutbutter tries to be The Hunter by locking horns into the next big project but secretly fits more and more into The Lord by trying to hang onto what he has.
  • Triang Relations: A major plot line is the evolution of Mr. Peanutbutter's relationship with BoJack and Diane, including how they perceive it to be and how it really is.
    • It starts as a typical example of Type 12: BoJack falls in love with Diane, who's in a committed relationship with his rival, Mr. Peanutbutter—who, for his part, genuinely likes BoJack and is always trying to become his friend, despite the constant rejection.
    • Then, it moves into a bizarre mixture of Type 2, Type 3 and Type 4 when they start working together: Diane's focused on BoJack, whose interest for her is growing, yet only for his biography and is truly in love with Mr. Peanutbutter, who yearns to be BoJack's friend much to the latter's displeasure and annoyance. At the same time, as feelings start coming to the upfront, both the horse and the Labrador end up in the same running path to win Diane's heart, putting them in conflict as rivals, all while Diane remains oblivious for the most part, especially regarding BoJack's real feelings.
    • AND THEN it gets really weird. Type 7 creeps in, thanks to BoJack starting to make actual efforts to win Diane over, while Diane remains devoted to Mr. Peanutbutter while at the same time seeing her relationship with BoJack grow as a strong bond of friendship. Followed very swiftly by Type 8 when both of her suitors's relationship evolves from a one-sided friendship to a two-sided rivalry to a reluctant partnership, complete with uneasy civil treatment.
    • Meanwhile, from Diane's point of view, it's more of a Type 10 with a more platonic edge: she's in a committed relationship but has feelings for BoJack in a way (sort of). As if it wasn't complicated enough, PB and BoJack's evolving interactions result in a slow slide into Type 11, with Mr. Peanutbutter's desire of BoJack's friendship turning out to have some possible romantic undertones as well.
  • Tritagonist: Along with Todd, Mr. Peanutbutter occupies this place in the series.
  • Troll: His role in his season 2 game show.
  • Underdressed for the Occasion: His formal wear is a t-shirt with a smoking print on it.
  • Unwitting Instigator of Doom: And a very prolific one. The Halloween parties Mr. Peanutbutter hoists on Bojack inadvertently kick off Bojack's alcoholism and Katrina's oppressive fiscal conservatism.
  • Uptown Guy: Mr. Peanutbutter (a rich TV star and celebrity) to Diane (a still up-and-coming author who came from a poor family). Season 3 establishes this even more — when they first met, Mr. Peanutbutter was an already rich celebrity going to extravagant parties while Diane was working at a cafe and working as a waitress at those extravagant parties to make ends meet.
  • Vitriolic Best Buds: He has this relation with Bojack, although it's only vitriolic on Bojack's part.
  • Where Were You Last Night?: In a show of Continuity, at the end of "BoJack Kills," Diane receives an angry call from Mr. Peanutbutter after not calling him back concerning where she was, explaining that he was worried sick. They talk, and she agrees to let him know where she travels to and when to expect her home.
  • Working with the Ex: Finds himself having to work with his first ex-wife (who he despises) after she offers him the chance to run for Governor of California.
  • Youngest Child Wins: He was the runt of his litter and is a wealthy, famous Hollywoo star.
  • Your Cheating Heart: He cheats on his new girlfriend Pickles with Diane. At first, he excuses it as a moment of weakness, but after the second time, he admits that he still loves Diane and isn't over her.
