From the publisher:
When the ever-curious Ralph spots Keith's red toy motorcycle, he vows to ride it. So when Keith leaves the bike unattended in his room one day, Ralph makes his move. But with all this freedom (and speed!) come a lot of obstacles. Whether dodging a rowdy terrier or keeping his nosy cousins away from his new wheels, Ralph has a lot going on! And with a pal like Keith always looking out for him, there's nothing this little mouse can't handle.
