All Stink wants is a guinea pig. And all his mother can say is NO. They already have a cat and a toad and they are NOT going to add a guinea pig to the menagerie if she has anything to do with it. Stink understands, but he really wants Astro, a blue-eyed, spiked-hair pig. Goodhearted pet store owner Mrs. Birdwhistle has taken in 101 guinea pigs that were being mistreated by a cosmetics lab and now she’s in a pickle. She needs to find homes for all the squeaking rodents and enlists the help of Stink and his punny friends. Along the Virginia highway, in a renovated camper—now pet store—Mrs. Birdwhistle introduces the young reader to the nuts and bolts of raising and caring for guinea pigs. Fans of Judy Moody and her brother Stink will find everything they love here—friendships, riddles, adventure and animals. Parents everywhere, beware! Lots of kids are going to be looking for the Squeals on Wheels bus so they can have a pig of their own. (Fiction. 5-8)
