Joe

Joe is a green, mean-looking shark with a propeller at the end of his tail who homes in on Kirby and tries to latch on to him, bite him, and absorb his health. He appears in Kirby's Dream Land 3 and is often found underwater.

In the anime
Joe is an ally of Kirby in the anime. He often cruises around the oceans of Pop Star, waiting for anyone hapless 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 group of Joes appears and chases after them both.

Trivia
Joe is not to be confused with a similarly-named character, Knuckle Joe.
