A monster makes quite an impression at his new school, but becomes so disruptive that Mr Jedd the Deputy Head bans him from attending. The children, however, miss his presence, and will work together in order to enjoy lessons with him again. A charming story written by CBeebies programme writer Tracey Hammett and illustrated by Jan McCafferty, Monsters Not Allowed! is a humorous tale of kindness and understanding, teaching children about inclusion, collaboration, and loving their differences.
