Mr. Peanuts’ teacher friend Rosie needs help preparing for the first day of school! The two squirrels go shopping for school supplies, set up the library and music corners, bring all the sports equipment out to the blacktop, and decorate the classroom. Mr. Peanuts even practices driving the school bus! But it’s not easy to be a teacher getting ready for a whole classroom of new faces. Will Mr. Peanuts and Rosie be able to pull together the room before the end of summer?
