Joe is a shark-like enemy only appearing in Kirby's Dream Land 3. It is a green shark with a propeller at the end of its tail who homes in on Kirby and tries to latch on to him, bite him, and absorb his health. It is often found underwater.
Joe is an ally of Kirby in the anime. He often cruises around the oceans of Planet Popstar, waiting for anyone hopeless and unlucky enough to fall into his waters. He looks unfriendly, but Joe is a friend of Kine's and can be a big help at times, seeing as how his favorite foods seem to be penguins and snails - in this case, King Dedede and Escargoon. There's more than one Joe; in the episode Island of the Lost Warrior, after Tornado Kirby blows the king and his servant snail into the ocean, a Joe appears and chases after them both.
