Iceberg Whales

Iceberg Whales are a species of creatures that live in the Frozen Wasteland

Description
Iceberg Whales are the only creatures large enough to eat Polar Ice Bears. They are always smiling and prefer frozen food, so they freeze their prey with their icy breath. Before they eat their meal, Iceberg Whales play with and sing to their food.

Appearance
Iceberg Whales resemble sperm whales and have icebergs on their snout.
