Glice

A Glice is one of three "gl" wheel-like creatures that travel around the edges of platforms. They first appear in Super Smash Bros. Brawl as enemies in The Subspace Emissary. If a fighter gets near a Glice, it opens up and emits a damaging aura that protrude icicles, which can freeze nearby characters.

In Super Smash Bros. for Nintendo 3DS, Glices appear in Smash Run, where they retain their behavior from Super Smash Bros. Brawl. They are weak to fire attacks.
