Ages 4 and up, you can experience Pettersson and Findus celebrate birthday by Sven Nordqvist. Findus wants to celebrate his birthday again, even though they have already celebrated it three times this year. Remembering that he came to Pettersson in a box, he suggests celebrating the "Findus-found-in-a-box birthday". Pettersson lets himself be persuaded and promises his famous pancake cake, but the flour has disappeared, his bicycle has a flat tire, and the key to the carpenter's shed is missing. When they have everything for the cake, neighbor Gustavson arrives with the news that the fox has been sighted again and he plans to deal with it soon, but Pettersson and Findus do not want to shoot it, only to properly scare it.
