Plot: Picking up where Shrek the Third left off, this animated, original, half-hour special finds Shrek (Mike Meyers) doing his best to get into the Christmas spirit. Having promised Fiona (Cameron Diaz) and the kids that this will be the best Christmas ever, the loveable ogre realizes that in order to succeed, he'll have to take a crash course in the holiday. His noble efforts are soon complicated, however, when Christmas arrives and old friends Donkey (Eddie Murphy), Puss in Boots (Antonio Banderas), Gingy (Conrad Vernon) and the rest of the gang decide to drop in for a surprise visit.
