Swifty the Arctic Fox, works in the mailroom of the Arctic Blast Delivery Service, but he has much bigger dreams. He yearns to become a Top Dog, the Arctic's star husky couriers. To prove he can do it, he commandeers one of the sleds and delivers a mysterious package to a secret location. Once there, he stumbles on a hidden fortress overseen by the nefarious Otto Von Walrus. The blubbery evil genius commands an army of oddly polite puffin henchmen. Swifty discovers Otto Von Walrus' villainous plan to drill beneath the snow-packed surface to unleash masses of ancient gas to melt the Arctic and become the world's supreme ruler. To stop this sinister scheme, Swifty enlists the help of his friends: PB, a neurotic polar bear, Lemmy, a scatterbrained albatross, Jade Fox, a brainy engineer, Leopold and Bertha, two conspiracy theorist otters and Magda, his curmudgeonly boss.
