Start your engines! As Mouse hops on his motorcycle to chase after Gorilla, the duo dashes through busy building sites, rolling railway stations, alpine avalanches, and more! Teeming with detail-rich scenes and slapstick humor . . . as well as every kind of comical car, boat, truck, and train . . . the book rewards and delights a gleeful poring over of its pages--while also ending up with a satisfyingly silly reason for all the adventure. Is Gorilla such a baddie after all?
