Stink #4 and the Great Guinea Pig Express by Megan McDonald
When three guinea pigs from the local pet shop make a great escape, Stink Moody and his friends Webster and Sophie spring into action. Ta-da! The Fantastic Fur Friends round up the little hairballs and bring them safely back to Mrs. Birdwistle’s shop, where they discover — oohla- la! — guinea pig pandemonium! Time for the Great Guinea Pig Giveaway! Stink and company hit the road aboard the Squeals on Wheels Express in a crazy quest to find good homes for 101 squealing, whistling, chirping, wiggly piggies. FUR-eaky!
