These jelly enemies were introduced in the windwaker, and have become rather popular, but one thing about them continually puzzles me. I know some Japanese words, and I am familiar with how they pronounce things, but, I don't know the true intentions of calling slime blobs ChuChus. I have heard Axle the beast call them "Choo-Choos", but I believe it is "shoo-shoo", because that's the Japanese word for the sound of squeaking, referring to the fact that they make squeaking noises, or that they're slime.
