These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Trio the Punch
Ear Worm: But not for a good reason. While the tunes themselves aren't that bad, your character's theme will play from the beginning of the game to A) the ending, B) the time you change characters, or C) the point when you you throw up your hands and walk away from the game in disgust.
Game Breaker: The sheep's curse. You only use it for one level (two if you die and continue in the stage where you fight the sheep), but the mini-sheep will one-shot all but the bosses, and pressing Down makes you invincible until you release the joystick. Enjoy your Breather Level.
Mondegreen: The win quote. Is it a mighty cry of "MAMBO!"? Or perhaps "HOT SAUCE!"? Who knows?
