This cheeky monkey is bananas about throwing beads everywhere!
— Cast Description • Kirby's Epic Yarn

Ooki is an enemy that appears in a few stages in Kirby's Epic Yarn. It first appears the the Fountain Gardens level, where it will throw beads around the are. They will throw ten beads of random value, after which they will sit around and do absolutely nothing. 

Under normal circumstances, Ooki does not attack Kirby, but while in the Tankbot form, they throw apples at the characters, which will damage the Tankbot.
