- What is a Treevipus? A fantastic creature with the head of a trunkfish, the body of a weevil and the tail of a platypus, of course! Here, a host of creatures presented in humorous pictures and informative captions take on new names, and a hilarious new identity when their heads, bodies and legs are swapped around as the pages are flipped. Tony Meeuwissen"s witty interchangeable text and beautifully detailed artwork combine to make an exceptional novelty book.
