Wilma the raccoon writes a beautifully crooked letter to Max, the little mouse. Wilma has baked cheesecake and wants to invite Max to join her. But oh dear: instead of reaching Max, the letter ends up with the old badger! Then it goes to the horse, the fox, the cat, and the sheep. Will Max ever receive his letter and be able to enjoy cheesecake with Wilma? Solve Wilma's letter from the first page and throw it from mailbox to mailbox. Then you'll find out!.
