What happens at the surprise party really surprises everyone! In fact, it is even remembered to this very day! Lucky the Cat and Ollie the Dog have been friends for a long time. They have enjoyed playing games and being together. When Ollie's fifth birthday rolls around, Mrs. Yorkie, Ollie's mother, decides to give him a surprise party in their doghouse. She invites all his doggie friends, but not Lucky. This makes it very difficult for Lucky who wanted to be included.
