Buried in a Jungle

Moominfamily and their friends have a great time in the jungle. The Hemulen is botanizing as fast as he can, everyone is eating tropical fruit and Moomin and Snorkmaiden play Tarzan and Jane, building a leaf hut. Suspiciously helpful, Stinky offers to get them some animals, too, so it will be more like a real jungle.
