The Lemmings are setting up a nightclub, with loud music and a mirror ball, in an igloo they have built not far from the cabin. The noise keeps Grizzy from sleeping. The bear confiscates the disco ball and throws the Lemmings away from him. They land in an ice cave where they discover a console that allows you to light up the stars in the sky and control the Northern Lights ... The sky begins to flash. The Lemmings transform the ice floes into an open-air nightclub!
