Biography
Swifty, an arctic fox, is an ambitious dreamer… but he’s a little too small and reckless to be considered anything more than an afterthought for the Arctic Blast Delivery Service. Stuck in the mail-room, he knows that he could be just as impressive as the Top Dogs, Totem’s star star husky couriers. Craving their fame, he’s never really given the chance to realize his full potential, until a mysterious package crosses his path and changes everything.
