Annie's dog is unhappy. When Fang is unhappy, everyone is unhappy. Especially Nate the Great. So Nate agrees to sniff out Fang's mysteriously missing Christmas mail. It's cold and snowy. But Nate the Great and his dog, Sludge, will try to solve this holiday case in time for Fang to have a crunchy, munchy Christmas.
A giant turkey is on the loose! Nate, the great detective, and his dog, Sludge, hear the news on the radio. But Nate doesn't want to take a case that everyone in town is on. Not even when Claude claims that he saw the turkey, then lost him in the woods. He holds up a turkey feather to prove it. Now Sludge wants the case. Claude wants Sludge, and off they go.
