Gummit

A Gummit is an enemy appearing in Super Mario Galaxy 2. They appear only in the missions The Chimp's Skating Challenge in the Freezy Flake Galaxy and The Chimp's Ultimate Skating Challenge in the Shiverburn Galaxy‎. In both missions, Gummits appear from small holes in the icy floor, and Mario or Luigi must skate over them (thereby knocking them out of their holes) to earn points.

Gummits come in three varieties: Gummits - which are worth ten points each, Golden Gummits - worth fifty, Spiky Gummits (known as Spiny Gummits in the Prima guide ) - which cause Mario or Luigi to fall backward and lose a few seconds, and are colored similar to Urchins. Unlike other enemies, Gummits can be bumped into without taking any damage.
