The funny thing about the caves is that these are plant people.  You'd think they'd be in forests more often but nope, underground or in grasslands!
A lot of said jerks are also cowardly (see: diving back into their planthousething).
River Zora are one of my most hated enemy types.  Bubbles/Anti-Fairies are another.  Screw both those guys!

This wouldn't be a derivative of the anime or any specific game.  Almost every game, anime, and manga is set in the general Digimon multiverse rather than a single world so you can get away with more stuff in regards to the exact setting. There are universal constants but events differ.

Sora.  Also KH1.  And depending on how you view Anti-Form it also is a thing in KH2.  And technically the events of Chain of Memories and most of KH2 since he doesn't have Roxas back inside him until near the end of KH2.

There are a lot of types of cartoons.  Do you mean silly or cartoon-physics?  Or something else?
