Scared Shrekless is a 26-minute computer-animated Halloween horror comedy television special, set shortly after the events of Shrek Forever After, that premiered on the American television network NBC on Thursday, October 28, 2010. Scared Shrekless was based on the children's book Shrek!, by the writer William Steig, which was published on October 17, 1990.
After Fiona and their three children scare away some teenage trick or treaters, Shrek, Donkey, Puss, the Three Little Pigs, the Big Bad Wolf, Gingy, and Pinocchio decide to tell scary stories. Shrek claims that whoever can tell the scariest story will be crowned King of Halloween. They go to the run down kingdom of Duloc where Lord Farquaad once reigned and get settled inside his abandoned castle and each take turns telling their story.
