Yogi Bear, Boo Boo, Huckleberry Hound and more Hanna-Barbera characters get lost and decide to spend Christmas by vising Casper, the friendly ghost. But soon they encounter a not-so-friendly ghost.

Businesswoman Sophie Throckmorton plans to sell the Jellystone Lodge, devastating the regular guests – including Huckleberry Hound, Augie Doggie and Doggie Daddy, and Snagglepuss – and it's up to Ranger Smith, manager Mr. Dingwell, and the newly awake Yogi, Boo Boo and Cindy keep the Christmas spirit alive amidst the mischievous attempts of two villains to ruin the fun.

The special is set in a town almost like in Disney's Lady and the Tramp, and it was Christmas Eve. In one house, a little boy named Timmy was read a Christmas story and tucked into bed. The resident mouse Gumdrop , while admiring the house all decorated for Christmas, noticed Timmy's letter to Santa on the floor. The letter must of have fallen off the table and never got mailed. So he and the family dog Gobber set outside to deliver the letter to Santa and save Christmas for Timmy.
