Mr Wolf gets together a band of former bad guys to do good deeds. There's Mr Wolf, Mr Snake, Mr Shark and Mr Piranha. They start by rescuing a kitten stuck up a tree and then head for the bigger challenge of liberating an entire pound of dogs. Success is guaranteed as long as they don't squabble too much and they don't eat each other or scare the animals they are rescuing to death. Humorous and clever series.
