Terrain

Terrain is a course variable that changes how different things in the level behave. There are 8 total different terrain types, although only 7 are actually used in-game.

Behavior

Terrain controls mainly how different surfaces behave within the level. Mostly, it impacts the noises different floors will make in-game (and many unused floor/terrain combos have unique sounds set). Floors that let you get stuck in them, like SSL and CCM, are also determined by terrain type. Additionally, slide levels have their own terrain types that overrides the slipperiness of floors to be that of a slide. Snowy water, such as in CCM or SL, also drains Mario's HP.
