An uninvited guest

Once on a quiet moon night, something strange made his way into the house of the muri-trolls. Baby Mu first sensed something was wrong - literally. Underwear gnawed at everything, including furniture, and it smelled very defiantly. To reveal the secret of the mysterious alien, the efforts of all the inhabitants of the muri-domo!
The world of murmar-trolls, invented by Tove Jansson, never ceases to surprise and delight. The “uninvited guest in Moomi-Dom” first comes out in Russian, and the staged photographs of the puppet mummy-doom and its inhabitants, which were created by Tove Jansson, Tuulik Pietile and Penet Eystul, were illustrations for this unusual book. And here a character appears, who is no longer in any story!
