Have you ever seen a mouse sneak around in your house? I did once. What if that mouse became your friend and you even let it play with your toys? In this book a boy lets a mouse ride his toy motorcycle. The mouse has all kinds of adventures. My favorite part was when the boy made a helmet out of a ping pong ball for the mouse to wear. I liked that because the boy was kind to the mouse. Read this book to find out the adventures of the mouse and the motorcycle.
