The famous children's writer Tove Jansson invented the Moomins and their friends, who soon became famous throughout the world. Do not deny yourself and your children the pleasure - take a look at the hospitable Moomin Valley. Soon, very soon, autumn will come. This means that Moomintroll and his mother need to quickly find a cozy place and build a house there. Previously, Moomintrolls did not have to wander through forests and swamps in search of housing - they lived behind people's stoves. But now there are almost no stoves left, and the Moomins can’t get along with steam heating... That’s why Moomintroll, his mother, and with them the little animal and the girl Tulippa are traveling in search of a home. But it would be great not only to find a suitable place, but also to meet Moomintroll’s dad who disappeared a long time ago! Who knows, maybe a big flood will help the Moomin family find each other again...
