Pupík, Hrýzek and the Christmas presents

It's Christmas Eve, and Pip and Nibbles the mice have finished their work. They've prepared fragrant parcels of sweets for Squirrel, Hare, Badger, Fox, Wild Boar, and Owl, and now they have one last task – to deliver them to their friends throughout the forest. When they return home from their deliveries, a nasty surprise awaits them. The sweets they had kept for themselves have disappeared! Who could have stolen them? Could the marten, to whose den the tracks in the snow have led them, be responsible?
