Chuchu

ChuChu Jellys are a jelly-like monster that appear in most Zelda Games. In 'The Legend of Zelda: The Wind Waker', when you defeat these somewhat annoying ChuChu's, you get green, blue, or red jelly to sell. Just like the color of the Jellys, the ChuChu come in all different colors; Red; Blue; Green; Yellow. These guys are easy to beat, just use your sword, and they should be gone in at least 3 shots.

See? They look really easy to beat. They sometimes might not. Why might they not? In Zelda The Wind Waker, they have electrical ChuChu's, as well as normal ones. In Zelda The Minish Cap, you've got big ChuChu's!
