Otis convinces his college buddies Donner and Blitzen to stop by the barnyard on Christmas Eve. During the visit, Otis accidentally gives Santa a cup belonging to Freddy, who is sick. When Santa comes down with Ferret Fever and can't finish his rounds in the county, which turns out to be his last stop on his Christmas Eve rounds, then Otis and the animals vow to make toys and deliver them by midnight to save Christmas. Meanwhile, Snotty Boy, not knowing he’s on the naughty list, really wants a Red Rider BB Taser that Santa doesn't bring him every year. So he sets a trap for Santa to make sure he brought his present.
