Scuttlebug

Scuttlebugs are red and orange spider-like enemies in Super Mario 64. They are large red, orange and yellow spheres with yellow pincers, red legs and red feet, and yellow-white eyes with red irises. They roam aimlessly and then run towards the player when they spot them. They do damage upon contact, and are defeated by being jumped on.
