A hilarious cumulative story about baking a 'pancake-cake' for the cat with three birthdays a year! When Pettson sets out to make Findus a cake, he finds that he's missing a key ingredient. This starts a hilarious chain of events resulting in Pettson distracting a bull, climbing through a skylight into his attic to find his fishing pole to fish the key out of the well, so he can open his shed, fix his flat tire, then ride to the store to buy some flour (and a new pair of overalls), then made a tasty cake for Findus!
