* Sometimes Mooks will get startled at the sight of you and run around in panic.
* [[https://www.youtube.com/watch?v=hAMNO2jOaz0 The pause screen music]], which has Wario loudly and obnoxiously singing "NAH, NAH NYEE NYAH NAAAAAAAAH! NAH, NAH NYEE NYAH NAAAAAAAAH!" in time to the beat. Every. ''Single''. '''''Time'''''.
** If you have the patience to [[https://www.youtube.com/watch?v=KIXU5tSu2h0 listen to it for 50 minutes]] -- Warning: It ''will'' get on your nerves -- [[EveryoneHasStandards Wario will actually apologize for the annoyance and stop]], leaving only the background theme.
-->'''Wario:''' (''long pause'') ...sorry.
* The instruction manual that comes with the game. It's written by Wario himself.
* Wario's [[PreMortemOneLiner signature quips]] when throwing or pile-driving an enemy:
-->'''Wario:''' Have a rotten day!
-->'''Wario:''' GET OUTTA HERE!
* The boss battle against Red Brief J has a funny moment. The way to hurt this bull is to wait for him to charge, and when he stops, you can ground-pound the platform and send him into the lava. What makes it especially amusing is [[OhCrap the way he looks teetering on the edge, with his mouth agape and waving his arms]].
* It's fully possible to trick [=DinoMighty=] into falling off the platform and damaging herself by jumping into the lava. How do you do it? By [[AgonyOfTheFeet hitting her feet with a pillar.]]
* As an EasterEgg, the description for the game's save data icon is [[ItsAllAboutMe "This is WARIO'S data".]]
* The MultipleEndings feature Wario in his throne with his castle in various states of repair depending on how high the score and number of collectibles is:
** The worst rank has Wario sitting in his throne outside in a dark forest with only a ''tent'' bearing a W emblem beside him and a campfire to stay warm while providing light.
--->'''Wario''': Huh? [[BigWhat What did you do!?]]
** The second lowest rank has a castle that's more of an army fort with walls made of sharpened logs, no ceiling, torches lighting the area, a couple banners and a flag. Technically a [[ExactWords castle]] if you squint, but Wario [[{{Understatement}} is not amused.]]
--->'''Wario''': [[YouHaveGotToBeKiddingMe You must be kidding]]! [[WhatTheHellPlayer This isn't funny, you idiots!]]
** The third lowest rank has a Medieval-esque stone castle with braziers lit to illuminate the throne hall he's sitting in, but still a significant downgrade from his old castle.
--->'''Wario''': I'm... I'm WARIO!! I can't live in something like this!
** Crossing into the top 3, the third highest rank shows a very wonderful-looking silver castle... and yet Wario still hates it, [[EntitledBastard since he's used to gold.]]
--->'''Wario''': What are you trying to do to me?!
