Moomintroll and Snorkmaiden are following a trail of green smoke as they serach for a Martian in the Observatory . . . but what will happen when they find him? Join Moomintroll and Snorkmaiden as they find mysterious things happening while they follow the smoke, past Stinky, Little My and some shrunken Moomins and creeps. Along the way, lift the flaps to explore rooms, peek into cupboards and peer behind doors. There are all kinds of wonderful things to find!

With simple text, things to spot and flaps to lift on every page, In the Observatory is the perfect introduction for little ones to Tove Jansson's world of Moominvalley.
