Already exhausted from a long flight, the flock wants to land, but Akka refuses to go to the forest on nearest island, until a storm forces them. The leader fears the legendary Bogey-beast, an evil spirit in that forest which allegedly makes every bird disappear on the night of the full moon, which is on hand. Only Nils has the courage to explore, and discover the strange phenomena on he island are the work of bats, who actually hold a party in a cave and welcome the flock to the dance floor.
