It's a special day at 3 Maple Street. It's Little Rabbit's birthday! His mother makes him his favourite breakfast. His sister has drawn him a picture. And, best of all, he's having a birthday party! His friends are invited, his father is decorating, and his mother is baking a cake. But that's not the only thing going on at 3 Maple Street today. The Cat family is moving in upstairs... the Fox family is having a new baby... Mr. Owl is trying to sleep... there's so much happening inside (and outside) this lively building, it's hard to keep track!
