An ocean sunfish who befriends Kirby in Kirby's Dream Land 2 and Kirby's Dream Land 3. He allows Kirby to swim more efficiently and synergizes with copy abilities in ways that can behave differently based on land and water.
After a number of cameos since then, he makes a return in Kirby Star Allies alongside fellow animal friends Rick and Coo, where the trio comes together as a Dream Friend. They were part of the first wave of post-launch Dream Friends alongside Marx and Gooey.
