Bolds to the Rescue [PDF ebook] 

The Bolds-the hyena family successfully impersonating as humans-have become legendary in the animal kingdom. Soon their house is full of visitors hoping to learn how to pass as humans too. There’s a crocodile who can’t quite tame her appetite, a poodle who wants to be a famous singer, and runaway racehorses hiding from their owner. With so many houseguests, the Bolds have their hands (ahem, paws) full. Can they teach these outcast critters to survive in the human world?
