Snufkin knows belongs to the Snorkmaiden. They arrive at the observatory, where they discover that the comet will be colliding in two days. On the way back home, Moomin saves the Snorkmaiden from a giant carnivorous plant, and they immediately fall in love with each other. Both Snorks join the group while they try to reach Moominvalley before the comet. Two days later, Moomin and friends meet the Hemulen and when a hurricane strikes them, they all fly to the Moominhouse with Snufkin's tent. Back home, they all decide to move to a cave Sniff had found for shelter. Sniff is lost during the move when he sees a kitten and begins to follow it with a piece of cake. When there are only minutes left to the expected moment of the comet impact, Moomin and Snufkin find Sniff, who is paralyzed with fear, and they carry him into the cave at the last minute. The comet almost crashes into Earth, but suddenly changes its course and turns away. The next morning, the sea returns and the characters celebrate on the beach, where Moomin gives Snorkmaiden a pearl he had found.
