Scale Lift

Scales are platforms present in the Mario series. When a player lands on one platform, the parallel one rises. If the player lingers too long on one platform, the scale breaks apart.

Super Mario Bros.
Scales make their first appearance in Super Mario Bros., where they are the main gimmick of World 3-3.

Super Mario World
While scales themselves do not make an appearance in Super Mario World, a similar platform named Mushroom Scales appears. As other scales, landing on one part of the scale causes the other to rise, though the Mushroom Scale does not break.

Super Mario Advance 4: Super Mario Bros. 3
Scales appear in Super Mario Advance 4: Super Mario Bros. 3, in the World-e level Caped Escape.

New Super Mario Bros.
Scales reappear in New Super Mario Bros. in World 1-5. They behave the same way as the scales in Super Mario Bros.

New Super Mario Bros. Wii
Scales reappear in New Super Mario Bros. Wii, where they are the main gimmick of World 6-4. Unlike the scales in Super Mario Bros., enemies and other items affect the scales with the player.

New Super Mario Bros. 2
Scales reappear in New Super Mario Bros. 2 behaving the same way as other games.

New Super Mario Bros. U
Scales appear in New Super Mario Bros. U, where they are the main gimmick of Scaling the Mountainside. Unlike the scales in New Super Mario Bros. Wii, the scales reappear in a short while after breaking.

Super Smash Bros. series
Scales also appear as stage elements in the Super Smash Bros. series; they react to fighters' weights and drop or rise at appropriate speeds. One appears in both of the Mushroom Kingdom stages of Super Smash Bros. and Super Smash Bros. Melee. A scale also appears in Super Smash Bros. for Nintendo 3DS, as part of the Golden Plains stage, though it is only available if the stage has scrolled to the right side.
