This is a great film to get you in the Christmas Spirit and this is the plot.
Yogi and his little pal, Boo Boo, are usually hibernating during the Christmas season, but this year they are awakened when Huckleberry Hound, Snagglepuss, Augie Doggie and Doggie Daddy come to Jellystone Lodge for the holiday. They are joined by Ranger Smith, hotel manager Mr. Dingwell, Otto the chef, and lodge owner Sophie Throckmorton and her spoiled brat of a nephew, Snively. The gang is obsessed with keeping Mrs. Throckmorton happy to keep her from closing down the lodge, which has become unpopular due to activity caused by Herman the Hermit, a grumpy Christmas-hating hermit who just wants to be left alone. After being embarrassed by Yogi and hurt by his aunt Sophie not standing up for him, Snively runs away and eventually joins up with Herman to ruin Christmas.
However, Yogi manages to thwart them every time. Cindy Bear also awakens from her hibernation, to help Yogi out (due to her love and concern for him). Eventually, Herman and Snively are forgiven, invited to the Christmas celebrations and they have a profound change of heart at such generosity of spirit. Then in the midst of the festivities, Santa Claus plummets down the chimney bearing a picnic basket full of food for Yogi. Yogi, however, falls asleep, due to his natural instincts of hibernation. Santa then says that Yogi and Boo Boo can have the basket when they wake up in the spring. With that, the partiers return Yogi, Boo Boo and Cindy to their caves for the rest of their hibernation.
