After four blockbuster films, a Christmas special, and a Broadway show, you’d think Shrek was running out of swamp steam. But that couldn’t be further from the truth, as DreamWorks Animations’ not-so-jolly green giant is heading back to the small screen for a spooky Halloween special. This Thursday, NBC will air Scared Shrekless, an ogre-style night of spooky frights on Shrek’s favorite holiday. Instead of the usual tricks or treats, Shrek challenges Fiona, Donkey, Puss in Boots and the other fairy tale characters to spend the night in Lord Farquaad’s haunted castle telling scary stories. The last one to be scared “Shrekless” will win. Check it out at 8pm this Thursday. If! You! Dare!
