Gummit

A Gummit is an enemy appearing in Super Mario Galaxy 2. They only appear in the missions "The Chimp's Skating Challenge" in the Freezy Flake Galaxy and "The Chimp's Ultimate Skating Challenge" in the Shiverburn Galaxy‎, with both missions relating to The Chimp in some way. In the said game, Gummits appear from holes in the icy floor, and Mario and Luigi must skate over them to earn points. Gummits come in three varieties: green, which are worth ten points each; gold, worth fifty; and spiky, which cause Mario and Luigi to fall back and lose time. Unlike other enemies, Gummits can be bumped into without taking damage.
