Bomp

Pushy Walls are the pushing, protruding stones in Super Mario 64. At the beginning of the level, they go through a pattern of pushing, trying to shove Mario off of the cliff, and to his death.

The beginning and end stone are thinner than the center stone. The eyes have a blue outline with blue pupils. However, in Super Mario 64 DS, no detail is on the rock. They appear in many levels including Whomp's Fortress and Lethal Lava Land.

Pushy Walls also appear in Super Mario Galaxy, but with a different, more Thwomp-like look, and a different face.
