Birger - the little Storsjö Monster makes it up

Winter is here. Birger wants to go up on land and play around in the snow, but he can't because it's too cold.
It's boring when you can't do whatever you want, thinks Birger. What shall I do now?
The sixth book about the little Storsjö Monster is about tidying, doing the dishes and making dinner in your own way. But perhaps even more about having fun when it's boring.
