Green Chu Chu

The Green Chu Chu wobbles after you, in an attempt to damage you. These are one of the weakest enemies in Majora's Mask and can be killed with a slash from the sword. You can evil roll into them as a Goron with spikes and destroy them, which is much more fun. They usually have items inside their bellies, which you can take after you have killed them. Bare in mind that these enemies reappear every few seconds, so don't waste your time killing them.
