Little Charlie has a birthday every year – always on the same day! There’s a delicious birthday cake with a candle on it, and everyone’s wondering what presents he’ll get this year. »Happy birthday!« says Mummy, giving Little Charlie a kiss and handing him a little round package. The doorbell never stops ringing. Grandma Nickel, Cousin Käthe and Little Charlie’s friends Friedrich and Wilhelm arrive in quick succession. They each bring a present: a red board, two blue discs, a red pole with a bell attached to it. »Thank you,« Little Charlie murmurs – he can’t help wondering what this is all about. But first they all sit down to eat carrot cake and drink cocoa at the big table. Well actually not quite all of them… Mama is missing. Whatever is she up to? »She has something very important to see to,« says Papa. And then the door opens and Mama comes gliding in on a red scooter with blue wheels. She’s just been putting it together next door! »Thanks!« cries Little Charlie, and he jumps on the scooter right away to do a couple of laps around the dining table.
