A spring platform is an object which appears in Super Mario World.
Description[]
A spring platform is made up of five green segments. It can propel Mario or Luigi upward in the manner of a Jumping Board or a Jump Block. As such, using a spring platform plays the same sound effect. A spring platform can always be found attached to the side of an object. Mario or Luigi can bounce higher from a spring platform the closer they stand toward the end of one. Spring platforms use different frames of animation depending on if it is jumped on either closer to the object or toward the edge.
In Super Mario World[]
Spring platforms can be found in three different levels: Vanilla Secret 1, Vanilla Dome 4, and Gnarly.
