Doofengung lives alone in a decaying cave, where he amuses himself by watching stalactites dripping. Every once in a while, he grows jealous of his more highly-evolved brother Ro-juh, and comes up with schemes to steal Ro-juh's home. He is generally thwarted by Bunka da Bunkaquan, though it turns out that Bunka has nothing to do with foiling Doofengung's schemes at all.
