It is Lisa’s birthday. At last - a mountain of colourful packets! Burning with curiosity, she unpacks them all - but what is that? A crazy chicken! And what’s rattling in the next box? What a surprise! A jolly baby is grinning at her. But the sweet baby turns out to be a little pest. Lisa now doesn’t have a minute for herself anymore. She tries everything to calm down the small wild thing, but the baby does what babies do. The baby screams, parps, pees, poops and still wants to be entertained. But the more Lisa tries, the more goes wrong. What a beautiful mess! The bay has fun, the children have fun too. It is a zany play about being little and about being big, about children and their parents.
