Captain White Claw is one of the companions in Skylanders: Lost Islands. Buying him will cause more Gold and Silver chests to appear in the Kingdom more often and pay out more.
Captain White Claw was marooned on a deserted island by an evil band of pirates for not being nasty enough. Stranded, he vowed that if he were to be rescued, he would only do good. Soon after, he was rescued by a sweet Mabu grandmother who lived nearby. "Oh, he's such a nice young man," she said.
