In this picture-book companion to Penny & Jelly: The School Show, Penny is invited to a slumber-under-the-stars sleepover! But there's one small detail that derails the dynamic kid-dog duo: pets allowed. Penny and Jelly have to think quick if the real Jelly can't go, then maybe a pretend Jelly can! A paper Jelly?
