Gummit

Gummits are enemies in Super Mario Galaxy 2. They appeared in both of The Chimp's ice skating challenges which were "The Chimp's Skating Challenge" in Freezy Flake Galaxy, and "The Chimp's Ultimate Skating Challenge" in Shiverburn Galaxy. In the two challenges, they would pop up from holes in the ice, and Mario or Luigi would have to skate into them. There are three kinds of Gummits: green, which give 10 points; gold, which give 50 points; and spiky, which knock one of the Mario brothers back. All kinds of Gummits can be bumped into without taking any damage.
