Moomin Desert Island

After a disastrous helicopter ride through a thunderstorm, the entire Moomin family is stranded on a desert island, the very island their ancestors came from! They make the best of it, hunting for their supper, exploring mysterious tunnels, and salvaging items from a wrecked pirate ship (including the Mymble!), but their ancestors don't let them live in peace and quiet for too long. Soon the whole island will have to deal with the explosive consequences of their ancestors' misbehavior.
