A new dinosaur sighting leads to a series of ingenious disguises and hilarious chaos! Both Raptor Road and Fossil Street are up in arms as a new dinosaur has been seen in the forest nearby. Mayor Boris imposes a curfew. But is it Dippy who has jumped ship from Flint Beastwood's gang and is disguising himself as a dragon? Or is it a vicious new carnivore that only Uncle Loops has spotted? When Darwin goes missing, the herbivores feel they must disguise themselves as trees (carnivores don't eat trees) and search for him . . . Jeanne Willis's madcap characters and story, with Arthur Robins' inspired illustration, are certain to tickle anyone's funny-bone!
