The kids of Class 5-B are under attack — by a vicious and cruel substitute teacher. Mr. Brittle is rude, impatient, and worst of all, he doesn’t like guinea pigs! Fuzzy’s kids are sad and anxious, all because of the horrible sub. Beloved teacher Miss Wills is out on jury duty for who knows how long. What’s a responsible rodent to do?
Take action! With the help of his fellow Class Pets, Fuzzy is going to boot this bad sub out of school — even if he has to risk whisker and claw to do it!
