Terrain is the type of material that a platform is composed of. Terrain can be in different colors and textures, and produce different footstep noises when characters and other objects step or land on them. Outside of cosmetics, terrain only has an effect on traction, as well as the behaviour of some special moves: the speed and the type frequency of Pikmin that Olimar plucks in Brawl varies with terrain, as does Yoshi's ability to accelerate during Egg Roll in Melee.

Melee terrains

None of the different types of terrain have an effect on gameplay outside of cosmetics, with the exception of ice and other slippery surfaces.

Colours taken from Melee's debug mode.

Brawl terrains

Basic The default terrain type. 100% 1 1 1 0.4 0.5
Rock The slowest terrain to pull Pikmin from, though even then the difference is slight because only part of the animation is affected. Relatively rare; only appears in Castle Siege part 3, Spear Pillar, the rock of Pirate Ship, and Target Test 2. 40% 1 1 1 0.4 0.5
Grass/Leaves In general, any sort of plant surface. 100% 1 1 1 0.4 0.5

Light metal Usually used for smaller/thinner metal objects. 80% 1 2 1 0.8 0.5
