Blythe jumps into Aunt Christie's new catering truck to bring it to a stop after the pets accidentally slip it into gear, sending it careening down the street, but everyone, from a police officer to Blythe's dad assumes she was taking the truck for a joy ride because Blythe can't and won't reveal how she knows it was really the pets who were responsible.

While hurrying to meet her friends, Blythe overloads the dumbwaiter and finds herself stuck in it along with Zoe, Pepper and Minka, leaving it up to Penny Ling and the boys to get them out before they drive each other crazy.
