Donkey’s Caroling Christmas-tacular is a five-minute short released as a part of the holiday program Donkey's Christmas Shrektacular, which was released on December 7, 2010, with Shrek: The Whole Story box set and Shrek Forever After.
The short takes place in the Candy Apple, the new version of the Poison Apple. Donkey suggests everyone sing Christmas carols. Donkey sings "It's the Most Wonderful Time of the Year". Shrek, Fiona, the Ogre children, and the army of ogres sing an ogre version of "Jingle Bells" (such as Bug Cocoon, Lick the spoon. Try our chicken slurp). Puss in Boots sings "Feliz Navidad", although he titles it "Fleas Navidad". Then everyone sings "Jingle Bell Rock" as "Fairy Tale Rock".
