Glice

A Glice is one of three "gl" wheel-like creatures that travel around the edges of platforms. It is encountered in the Subspace Emissary. If the fighter approaches one, it emits a damaging aura that protrudes icicles, possibly freezing the character.

Glices reappear in Super Smash Bros. for Nintendo 3DS as Smash Run enemies, behaving like they do in Super Smash Bros. Brawl. They are weak to fire-based attacks.
