It is Findus' birthday, so Farmer Pettson wants to bake a big stack of pancakes for the cat who has three birthdays a year. But how can they get the eggs when the bull is in the way? But before he can start baking, Pettson has to fix a puncture on his bike, find the keys to the shed and distract Anderson's bull. Only then can he bike to the shop to buy flour for the pancakes.
Findus and Pettson live in a ramshackle red farmhouse in the country, with a henhouse, workshop and woodshed. Their world is a fascinating, magical one inhabited by tiny creatures who move Pettson's tools about when he isn't looking.
