An enormous iceberg floats by the coast of Diamantina. The animals who are more used to colder climates, such as Noah and the Problem Walrus, are delighted by the sudden cold snap the iceberg brings, but everyone else tries to escape the cold by sleeping in the Fire-Bowl chamber. Upon discovering that there is a deep crevice within the iceberg, Gorm and the frogs devise a plan to trap the animals inside, so when the iceberg leaves it will take them with it.
