On the topic of cartoon physics keep in mind that this applies to [i]everyone[/i] in the Mario-verse but mostly seems to touch on "Rule of Funny" tropes (while Kingdom Hearts seems to restrict it to Black-and-White Era Disney characters).  Think of the scene from the Who Framed Roger Rabbit movie where the bunny could only slip his hand out the handcuff when it was (from a bystander or troll's perspective) of being funny when he helped hold the table in place.

Then there's weird stuff like air/food/water ballooning up someone and hammers harmlessly burying a person in the ground to pull a Bugs Bunny style underground travel trick or to flatten them like a crushed can that somehow can still move in spite of being squeezed tight like a pressured metal spring.

So if the character is more along the lines of a 'comedy sidekick' they may be able to work the physics more often to their advantage/amusement but most might have some passive effects going on.
