Original game
- The title screen has a hilarious detail: wait a short while, and King Dedede will get the rest of the group's attention and pull a stupid face. The priceless part is their reactions. (Bandana) Waddle Dee laughs, Kirby is confused, and Meta Knight just looks plain embarrassed and shakes his head.
- In Multiplayer mode, every character can fly. Kirby and Dedede inflate themselves, Meta Knight has wings... So logically, Waddle Dee flies by awkwardly squatting repeatedly in what can only be described as "Infinite Double Jumps". It truly is a sight to behold.
- Even better? This carries over to Star Allies, with numerous characters doing it.
- In the last cutscene, Kirby and his friends are on Planet Popstar. Kirby wakes up and sees Waddle Dee and Meta Knight nearby. They find Dedede stuck in the ground headfirst. He spends the rest of the scene with a flower stuck to his head.
- Grand Doomer's entrance. Kirby grabs the seemingly unguarded mast, with the proper Item Get! theme... then it flies away, Letting the Air out of the Band in the process. Kirby's expression of joy vanishes as if to say "Wait, what?" before he suddenly drops to the floor. After that, Grand Doomer forms around the mast, and then the fight begins.
- Ultra Sword occasionally pulls out a paper fan and a huge fish. The fish being a Visual Pun just makes it even funnier.
- In the cutscene after defeating Landia, while Magolor is explaining his betrayal, Dedede keeps a hilarious Jaw Drop throughout the whole scene.
- The Deluxe version of the cutscene lessens the jaw drop but gives him a hilariously bug eyed set of Wide Eyes and Shrunken Irises.
- And then later, as Magolor leaves for Dream Land, you can also see Waddle Dee flailing his stubby arms.
- It's also weirdly amusing that Magolor takes the time to say he genuinely appreciated Kirby and co.'s help repairing the Lor, only to turn around and proclaim their home to be the first to bow to him as wearer of the Master Crown.
Magolor: You even helped me repair my Starcutter! I really did appreciate that, by the way. Anyway...MWAHAHAHAHAHA! The time has come for your planet...No! The time has come for the ENTIRE UNIVERSE to bow down to me! - The opening cutscene, mainly for Meta Knight as he attempts to ignore Kirby and King Dedede's antics and read a book.
- When Kirby and co turn to look at the bright light in the intro, you can see Kirby quickly turn back to the slice of strawberry shortcake that Dedede was chasing him for.
- Everyone being played does the Kirby Dance in this game when the time comes. You get to see Meta Knight moonwalk.
- For most of the cloud levels of the Goal Game, your characters happily dance. If you land on the lowest level cloud, 7, your character begins the dance happily but end the dance looking noticeably displeased — Kirby, in particular, has his eyes half-lidded and shrugs at the camera instead of posing.
- Meta Knight, quite possibly the rawest force of badassery in the Kirby universe, dog paddling around on the surface of the water in a cute purple inner tube. And wearing a scuba mask over his regular mask when swimming underwater. This is retained in Planet Robobot and Star Allies, too.
- Sometimes when beating a boss and collecting a piece of the Lor, Dedede will pull the most sour of faces at Kirby after the dance.
- The Puzzle Swap picture for this game involves Waddle Dee, Meta Knight, and King Dedede (in that order) jumping onto Kirby like a tower as he runs past them, only for Magolor to appear from his ship, jump onto King Dedede, and cause them all to fall. Kirby can apparently only balance three other beings on top of him at a time.
- The instructions for Bomb Kirby. In particular, the Self-Destruct one, in a morbid way. "Bomb Prep... do nothing."
- It's possible to kill your friends with Sleep.
- For something that was probably hidden from the general public for years, when Kirby talks to Magolor in his ship more times than what would normally be necessary (8 times in a row, specifically), Magolor starts getting... a bit impatient with him.Magolor: Kirby! Dude. Seriously. Hurry up and finish your quest already. If you don't actually help me out, your offer to help me out is kind of mean... SO HURRY UP AND HELP ME OUT, KIRBY!Magolor: Kirby, it may seem like I'm just hanging out here, but I'm pretty busy. I'm way behind on my chores, and I really need a haircut. So please stop distracting me and get on with your adventure!
- One of the pictures shown in the special credits unlocked by completing Extra Mode is King Dedede looking, well... Very high.
- Enemies you defeat with a Super Ability will sometimes be flung into the screen.
- Egg Catcher (a returning sub-game from Kirby's Adventure) has Kirby and King Dedede catch the eggs via eating them, but Meta Knight and Bandana Waddle Dee, being the less voracious and more sensible of the four — not to mention them lacking visible mouths in the first place — instead opt to hold up straw baskets.
- The dramatic twirl and "ouch!" Kirby gives when he gets knocked out in Samurai Kirby is surprisingly funny as well as cute. It's almost as if he's trying to say "I'm Okay!" after taking what at first looks like a fatal blow.
- While Magolor's betrayal was a huge surprise in the original game, it was already pretty well-known by the time the remake came out... so, the writers decided to drop a lot of the subtlety and make some of his dialogue hilariously transparent.Magolor: I'm amazed at how kind everyone is! You're all such easy targ— Er, I mean, easy-going folks!Magolor: Truth be told, I want to hear the screams of every living being in the universe... Screams of JOY, that is, as they visit my very own amusement park!
- Just like in the original game, Magolor gets unique dialogue if you keep talking to him repeatedly. However, in the demo version of the game, he may lampshade your repeated attempts to get more dialogue out of him.Magolor: Hey... Kirby. I imagine you're hoping I'll say something really clever and/or insightful if you keep talking to me, but... I'm fresh out of words. Consider me an ellipsis, if you will. An infinite series of dots ever repeating across a vast expanse of sweet, unknowable silence. We'll yak it up another time, ya? Hee hee hee!
- The Dress-Up Mask system. Some masks are cute. Some are sad. Some are creepy. And some are just...weird.
- There is nothing stopping you from using a player character's mask with that character. So you can make Kirby dress up as... Kirby. And because the Kirby Mask doesn't change expression, certain cutscenes can make it look like Kirby has no reaction to what's going on.
- One of the Masks is... Marx Soul from Kirby Super Star Ultra. The infamous horror of the second of the Kirby revenants is sort of dulled when it's slightly chibi-fied and placed on Kirby's face.
- Representing Kirby and the Forgotten Land, alongside the Beast Pack and Elfilin, is Cone-Mouth Kirby. Because it's only of the face of the form rather than the entire body, it looks more like Kirby trying to shove a gigantic graham cracker into his mouth.
- Susie has an alternate mask design called "Weekend Outfit", consisting of her in a beret, red glasses and a different hairstyle. It's an amusing (if not adorable) image picturing the infamously cold Susie enjoying a day off with a latte or the like.
- A number of the masks also have sound effects, overwriting the sounds of the character when used. So you can make the mighty King Dedede... use the same squeaks as the average Waddle Dee. Or put on the Hyness mask to replace Kirby’s adorable noises with the over-the-top yelling of Shigeru Chiba.
- Meta Knight is so dedicated to keeping his face covered that he puts masks on over his current mask. It’s even funnier if he’s wearing two Meta Knight masks. Take him for a swim and watch him up the ridiculousness by putting a scuba mask over the mask that’s on top of his default mask.
- With all of the major characters receiving an alternate mask along with their default one, Taranza's alternate mask is... Sectonia's original form. Some fans have depicted Magolor pranking Taranza with the mask with... expected results.
- Give Kirby the Zero mask. Acquire the Water ability. Use Down B. Laugh as the mask makes it look like Zero is crying Ocular Gushers.
- The fact that the Final Boss of Magolor Epilogue is essentially Whispy Woods on steroids, taking the Recurring Boss Template’s Memetic Badass status as of the latest titles to its logical, if crazy conclusion.
- The Final Boss theme in the Magolor Epilogue is called “Mistilteinn, Tree Crown without a Ruler”, a suitably epic name for orchestral final battle music... unless you know that Mistelteinn, or mistletoe in modern English, is Old English for “(bird) dung twig”. Suddenly seems a lot less epic...
- Magolor Epilogue becomes several times more amusing when you realize that — since it ends with him taking the Gem Apple to the Dream Kingdom — it is essentially the story of him discovering and establishing capitalism.
