Back to school with Cat and Mouse. Mouse is all set for his first day in Mr. Monkey's classroom. Cat took him shopping, and now he has new clothes, a new book bag, and even new shoes. Mouse is very excited -- and a little nervous, too. He is very glad that his good friend, Cat, will be going to school with him. But when Cat sees all her friends from last year, she leaves Mouse all by himself to face his first day of school. Now Mouse must be very brave and meet his new classmates, his new teacher, and even the lunch lady in his new school.
