Humphrey has a pretty good life as a class pet in Room 26. He gets to learn right along with the students and he gets to go home with each of them on weekends. All is good until classroom teacher, Mrs. Brisbane, returns from a long absence and declares her dislike of small, furry creatures. Uh oh! Humphrey’s situation is in jeopardy unless he can show Mrs. Brisbane what a likeable, helpful creature he is.
