Shrek is bored on Halloween, and wants to have something scary. The power of Thriller gives him more than he bargained for.
Lord Farquaad was eaten by the dragon, but his ghost has returned, and he's still evil. With the help of his henchman, Thelonious, he kidnaps Fiona. Shrek and the donkey set out to save her, with help from the dragon, before she goes over a waterfall on a raft.
