Donkey suggests everyone sing Christmas carols in this Shrek-tastic musical. Donkey sings "It's the Most Wonderful Time," while Shrek, Fiona, the Ogre children and the army of ogres sing an ogre version of "Jingle Bells." Puss in Boots sings "Feliz Navidad" but calls it "Fleas Navidad." Then everyone sings "Jingle Bell Rock" as "Fairy Tale Rock."
