Roturret

A Roturret is a mechanized skull with a giant arrow for a body flanked by two guns. It is encountered in the Subspace Emissary. It attacks by shooting with its guns. When hit, it will face another direction, but very soon, turn back to face the player and continue shooting. It has a blind spot in its center.

Roturrets return in Super Smash Bros. for Nintendo 3DS, in the 3DS-exclusive mode Smash Run, behaving identically to the previous game.
