Arctic Tale is the story of a polar bear named Nanu and a walrus named Seela. They start as babies. Nanu and her brother hunt on ice, but Seela spends the days when she's young going on clam hunts. The clams can even "fly" away, leaving Seela and her mother, helper Auntie, and the rest of the herd to catch the ones that stay on the ocean floor.
Then Global Warming begins to disturb the life of these arctic animals. The adorable Ringed Seal pups are left on the ice to the male polar bear's advantage (he later eats them). There is not enough snow for digging birthing caves. The ice is too thin for Nanu's mother to go hunting. An entire walrus herd struggles to survive on a tiny melting iceberg. Finally, they take refuge on Rock Island, which doesn't have much ice, until it is time to go home when the ice has frozen back again. Then, Nanu finally contacts a male polar bear after avoiding them most of her life (in a very playful way), and Seela gives birth to a walrus of her own.
