Prepare for a trilogy of Halloween treats in this year's terrifying Treehouse of Horror! First, punk rock pixie and Go-Gos founding member Jane Wieldlin (Lady Robotika) leads Marge down the path of the walking dead; then, Zander Cannon and Gene Ha (Top Ten) offer up a remake, Simpsons-style, of the classic horror flick Nosferatu; and finally, indie artist Jim Woodring (Jim) helps Bart uncover the truth behind the biggest mystery in the history of horror comics.
