Diagonal platform

A diagonal platform  is a type of lift that appears in Super Mario World.

Super Mario World
In Super Mario World and its reissue, diagonal platforms appear in Chocolate Island 4 and in Valley of Bowser 3. They are dirt lifts with grass on top that are placed and move diagonally. They are not slipped on like the Semisolid Platforms' slopes, but Mario or Luigi can slide on them.

Super Mario-kun
Diagonal platforms appear in two occasions in the Super Mario-kun manga: in Volume 3, when Mario, Luigi, and Yoshi escape from an electric Spike Top, and in Volume 4, where they use one to knock Kamek out.
