Pepper receives a pair of clown shoes stuffed with pistachio pudding in the mail. She shows it off to the other pets, but they prefer to play with the cardboard box it came in. When questioned, Sunil points out that Pepper had worn pudding-related gags into the ground. Blythe suggests trying comedy without pudding-related props, but this just stumps Pepper until she takes a breath of fresh air outside of the day care room and makes a snarky comment about a visiting bulldog's drool. The other pets find it funny, so Pepper tries some more of these remarks about Mrs. Twombly and then the other pets. Pepper ditches pudding jokes to go into stand-up comedy as it proves popular with the other pets—except for Penny Ling, who finds Pepper's jokes hurtful. Minka lets her know that everyone is perfectly fine with Pepper's insult comedy.
At P.E. at school, the Biskit Twins are forced to play basketball and go up against Vi, who curb-stomps them at the game and repeatedly insults them. Blythe, watching from the sidelines, reaches her limits and tells Vi off, making her leave. The Biskit Twins thank Blythe for defending them and, declaring her their new BFF, drag her away. Blythe gets some time with her normal friends at lunch, but the Biskits serves Blythe an RSVP through their butler. Blythe initially wants to tell them she will decline their invitation, but Blythe gets forcibly seated and her attention occupied by the butler's performance cooking. When she remembers her friends again, she turns around to see they had left the cafeteria without her.
Back at The Littlest Pet Shop, Pepper's jokes come out faster and now strike at the others' sensitive points, such as Russell's weight and Vinnie's intelligence. One by one, they stop laughing at Pepper's jokes. Pepper tries a jab at Penny, but Penny is nowhere in sight. Pepper eventually finds her and, after verbally attacking her despite Russell's protests, causes Penny to cry. The other pets rush in to comfort her, and Pepper realizes the nature of her new comedy.
Blythe lets Youngmee and Sue know that she's had it with the Biskit Twins, but before she can finish, she receives an iPad used solely to display a video invitation for Blythe to hang out with them. Bedazzled at their presentation, Blythe ditches Youngmee and Sue and spends some time in the Biskit limousine and at a department store shopping for clothes. Their influence grows on Blythe, and before long, she looks, talks, dresses, and acts like them. When Blythe joins them in making fun of someone in that department store trying on makeup, she becomes horrified upon finding out that this someone is her friend Sue. Blythe immediately cuts ties with the Biskit Twins, and while the twins accept that, the butler confiscates everything the Biskit Twins had given Blythe during her time with them. Sue discovers Blythe, and Blythe apologizes, repairing their friendship.
Pepper attempts to console Penny herself by doing harmless stunts, but Penny remains emotionally hurt. Blythe returns to the pet store, and seeing what happened between Pepper and Penny, Blythe suggests for Pepper to apologize to Penny. Although Pepper begins with a joke thinly disguised as an apology, she quickly corrects herself and delivers a sincere one, admitting that she was only thinking of herself. Penny accepts and even has a pistachio pudding pie ready to hit Pepper's face with, bringing back Pepper's classic comedy.
This episode contains examples of (YMMV entries go here):
- Absentee Actor: Roger is completely gone from this episode.
- Brick Joke: The Biskit Twins refer to their butler as "garçon." Blythe remembers it later as "Au revoir François."
- Crippling Overspecialization: Pepper had only done pudding-related gags before. They got old in a hurry.
- Easily Forgiven: Despite the Biskit Twins chronically antagonizing Blythe, the moment Blythe stands up to them against someone even meaner, they instantly declare Blythe their best friend. Taken to a more dramatic degree in the third act, when apologizing to Sue and Penny was all they had wanted.
- Everybody Laughs Ending: Justified, as Pepper is once again funny to everyone.
- Evil Laugh: Blythe develops one after spending too long with the Biskit Twins. By the time it's all over, she wishes it hadn't come out of her.
- Fisher Kingdom: Before long, Blythe starts talking, wearing makeup, and maintaining a deadpan expression like the Biskit Twins. Bonus points for Fisher being the twins' father's name.
- Food Porn: In-universe. While the butler's food doesn't look any different or more detailed than the rest of the show, Blythe is amazed at both its appearance and the butler's display.
- Frothy Mugs of Water: Lemonade seems to be a stand-in for champagne, served in champagne glasses and swished around before sipping. Justified, as this is among teenagers in public.
- Gratuitous French: The Biskit butler and anything related to him.
- Hammerspace: When the Biskit Twins confiscate Blythe's things they had given her, we see it includes bundles of cash, knee-high boots, a wicker basket, and a bicycle.
- Huge Schoolgirl: Vi Tannabruzzo. It turns out she is very sensitive about it.
- Innocently Insensitive: Blythe accidentally insults Vi over her height.
- Pepper unintentionally offends everyone with her insult comedy, particularly Penny.
- Inelegant Blubbering: Done by Penny after Pepper hits her with an insult comedy joke.
- Just for Pun: When Blythe suggests a new schtick, Pepper holds up a pair of sticks and says she already has them. Naturally, they're stuffed with pudding.
- Lampshade Hanging: When Blythe talks about how abbreviating her sentences into acronym saves time, Mrs. Twombly points out that Blythe wastes more time having to explain them.
- Like Is, Like, a Comma: Apparently, the Biskit Twins also add "like" into their writing. Later on, Whittany inserts "like" as a filler right before "like" as a verb.
- My God, What Have I Done?: The last four words, spoken word for word by Pepper after making Penny cry.
- Blythe later gets one each time she momentarily lapses out of Biskit Mode.
- Non Sequitur: Previously, Pepper had a preference for putting pistachio pudding into every possible punchline.
- Ocular Gushers: Taken Up to Eleven with Penny. An earthquake precedes it, then a tidal wave. Sunil puts up an umbrella to no effect. Penny's tears literally flood the day care room and almost drown Pepper.
- Pets Prefer Boxes: The other pets found the cardboard box and its packing peanuts more fun than Pepper's pudding-filled shoes.
- Shake Someone, Objects Fall: How the butler gets back the items the Biskit Twins gave Blythe during their friendship.
- Shout-Out: In the second act, Pepper hops like Pepe LePew when she starts searching for Penny. She does it again in the third act when she gets an idea about cheering up Penny.
- The butler briefly dances The Pony as seen in "Gangnam Style" when at the department store.
- Solo Duet: Brittany and Whittany are both voiced by Shannon Chan-Kent, meaning she sings much of "BFFs" by herself.
- Sting: Each time Pepper tells a joke, at least until they start offending her addressees.
- Villain Song: "BFFs."
- What the Hell, Hero?: Pepper is given this by all the other pets after she goes too far with her insult comedy.Russell: Pepper, you've gone too far!
- What Happened to the Mouse?: Among Blythe's true friends, we only see her apologizing to Sue. Hopefully, Youngmee and Jasper were not left out of the loop.
- We don't see if Blythe ever apologized to Vi after accidentally hurting her feelings.
