Cascading Stone

Cascading Stones, also described as falling stone blocks or falling blocks , are platforms of various shapes and sizes in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. When stood upon by Yoshi, they fall down into the ground, or off the screen. They shake when Yoshi stands on one, indicating that they will fall. They appear in a few levels, but mostly in the level Visit Koopa And Para-Koopa.

The rocks make a reappearance in Yoshi's Island DS, where they appear mainly in World 4-1, Rock 'n' Fall. They also reappear in Yoshi's New Island as a feature of World 2-1, Koopa Canyon. In the former, similar obstacles known as Sliding Blocks appear in World 3-7, Tap-Tap's Sunken Cave, and World 4-7, Teeth-Chattering Chill Zone. The latter game also includes similar obstacles in World 6-7, Crumble Rock Rumble.
