It starts out with Boris Bulldog walking through the town, delivering some post and he has something special to deliver, an invitation for Bonnie, Edward and Max to Lionel Lions fancy dress party where there'll be a prize for the most unusual costume. They receive the letter and Max reads it out to Bonnie and Edward, the idea of the contest makes them think of what they'll dress up as, Max decides that he'll dress up as a car and walks off making car noises. Bonnie comments "How's he going to be a car?" to which Edward replies "Probably going to grow wheels," Max returns in a car costume saying "Beep beep" and 'drives' in-between Bonnie and Edward.
