The Bold family seems fairly normal: they live in a nice house, the parents have good jobs, and they all love to have fun. One slight difference: they're hyenas. That's right—they're covered in fur, have tails tucked into their clothes, and really, really like to laugh. For years, the Bolds have kept their true identities under wraps. But now the neighbors are getting suspicious, and the Bolds are getting homesick. During a trip to the local wildlife park, they meet an old hyena who is going to be put down, and the Bolds have to act fast to save him—without revealing their secret!
