Publisher Annotation: An ensemble cast of Squirrels, Acorns, and pop-in guests hosts a page-turning extravaganza. Each book features a funny, furry adventure AND bonus jokes, quirky quizzes, nutty facts, and so, so many Squirrels. In The FRUSTRATING Book!, Zoom Squirrel wants to feel brand new emotions. The Squirrel pals know just what to do! But what happens if Zoomy doesn't like these new feelings? Do you know more about feelings than the Squirrels...
