Gummit

Gummits are enemies that appear in Super Mario Galaxy 2. They, however aren't really considered enemies,

because they cannot harm you. You can kick or stomp them. On missions, the Chimp asks you to kick as many Gummits as possible to get 500/600 points. Normal gummits are 10 points, golden gummits are 50, and spiked gummits are worth none and knock you out of skating, severely hindering your score.
