* Several of Olimar's treasure hoard notes in the second game, as well as Louie's cooking notes.
** The suspicious [[MarioPaint blue color paint]] that Olimar used for the ship. Olimar gives a nutshell of what happened after.
--->"But did it thank me? Nooooo."
** Louie's notes on the Caustic Dweevil.
--->"Inedible. Effects of consumption include uncontrollable arm-flailing and enthusiastic dishwashing."
** Olimar's notes on the Waterwraith, just because of how [[GenreSavvy correct it was in how the player would react to it.]]
*** Louie's notes, for the exact same reason, only [[Radar/{{Pikmin}} couched in medical-sounding euphemisms]].
** Olimar's notes on the Silencer, namely how he complains about the President.
*** Made even funnier because the Silencer is obtained in the Wistful Wild - that is, ''after the President joins your party''. One can only hope the President never reads Olimar's journal...
** Louie's notes on the Mamuta.
--->"Inedible. TastesLikeChicken.'
** Louie's notes on the Queen Candypop Bud.
--->"Eating this flower leads to spectacular, breathtaking indigestion."
** Olimar finds the Paradoxical Enigma, a severed rubber duck's head, to be a stunning work of art. When he finds a more complete rubber duck in the Shower Room...
--->"The first time I laid eyes on this hideous treasure, I though it was a giant aquatic monster! It took me several terror-filled seconds to realize that it's just an ugly statue. What a relief... I was ready to run all the way back to Hocotate!"
** It turns out Olimar likes karaoke, which his family apparently looks down on him for.
* A few of the ship's sales pitches count too.
** For "[[GettingCrapPastTheRadar Innocence Lost]]":
--->"Think back and remember the starry skies of your youth...Innocence...Every being once possessed it, but lost it over time. This star is the shape of that precious memory. [[MoodWhiplash All major credit cards accepted]]."
* The second half of the battle against the Waterwraith.
* The Pikmin going and beating up the Bulborb in the Good Ending of the first game.
* The bonus video for completing challenge mode shows us some more detail about the reason for the plot. [[spoiler:Louie was lying about the ravenous space bunny. ''He'' ate the ''entire shipment of golden pikpik carrots''.]]
* Some of the ship AI's reactions, especially after you make it store a deceased enemy, attempt to enter the Submerged Castle, and after it [[spoiler:becomes gold plated]].
* Enemies falling off the side of the rusty metal stages. Especially if they're a Bulbear marching after your Pikmin so blindly that it walks out onto nothing and falls.
* Plenty of the letters you recieve. Highlights include the President realizing he accidentally took a loan out with the [[LoanShark All-Devouring Black Hole Loan Sharks]], the President accidentally eating all the cookies that were for Louie, spam letters, and Olimar's family attending a performance and falling asleep during it.
* [[ThePigPen Doodle]][[{{Fartillery}} bugs]].
* If you're not going for a NoCasualtiesRun, try finishing off a boss by poisoning it. It will only cause minor damage, but if you pull this off, it's your personal CrowningMomentOfAwesome '''and''' [[CrowningMomentOfFunny pretty hillarious to boot]].
* In ''2'', the ship writes sales pitches for all the treasures found. Even the food.
--> "The consistency of the half-cooked yolk says "Mmm! Good!" It is packed with nutrients, too. I can sell it, but I have never eaten it. I am UNABLE to eat it. Not even a nibble."
* Both notes on the [[KillItWithFire Flare Cannon]]. The Ship says it should "never be used to cook sausages". Olimar says [[BigEater Louie]] keeps trying to use it to cook sausages.
* In ''3'', all Pikmin can throw bomb rocks now. Those who do throw the bomb and run away screaming the Pikmin equivalent of "Run away!".
* Charlie's odd fascination with his Rubber Ducky becomes an amusing RunningGag. It's especially funny when [[spoiler: Louie]] runs off with it.
* Between days in ''Pikmin 3'', the crew mates can speak to each other. These random conversations can be quite funny.
** Alph goes on about Charlie's legendary acts of heroism, such as "Operation: Rubber Ducky Stucky" and "Operation: Rubber Ducky up a tree".
** Brittany tells Alph that she thinks that Pikpik carrots are gross.
* After you save Charlie, his rubber ducky can be seen floating around aimlessly inside the ship, even floating past the map sometimes. [[spoiler:When you capture Louie after he stole all your juice, he's tied up and does the same thing.]]
* When the ship crashes at the beginning of the third game, you can hear the laugh of the {{Duck Hunt}} [[TheScrappy Dog]].
