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.
