World ex. China, JapanIn Grandma's house Peter and Anna come across an old chest containing lots of old clothes, hats, necklaces and other things. Great stuff to dress up as grown-ups. "Let's pretend we are a family", Anna suggests. "You are the father, I am the mother, and we have one child", she continues. Since no doll is available, Anna takes needle and thread and a little piece of cloth and makes one: Here it is, their little child. Anna and Peter call it Bimbulli. Using an old button-box they make a carriage for Bimbulli. They decide to play "hide-and seek" when their grandmother calls for lunch.
Left alone Bimbulli decides to go on playing on its own and hides in a bag full of potatoes. Short time later a hen discovers Bimbulli. Taking it for an egg, the hen picks Bimbulli up and takes it to the nest. A little chicken is just about to hatch out of its egg. Bimbulli and Prince Chicken soon become close friends and decide to go for a walk. Bimbulli puts Prince Chicken into the button-carriage, and off they go. Out in the garden it is a bit slippery and all of a sudden the carriage with Prince Chicken in it falls into the nearby water. Bimbulli trying to help Prince Chicken jumps into the water, too. Now the two of them are drifting on the water. Suddenly it starts to rain. Bimbulli and his little friend take shelter under an old hat. A little frog seeks refuge there as well. Soon other animals join them: a little mouse, a stag beetle, a butterfly, a hedgehog, a squirrel, a caterpillar and two ants. Although their little boat is quite packed, somehow they manage. They sing songs and play games. Thanks to a glow-worm which has joined them they even have some light there. Then they all fall asleep. Next morning they wake up early and make their journey back home again. Peter, Anna, and Prince Chicken's mother can hardly wait for the runaways to get back.
