Free candy! Yay!
Free candy! Yay! is a special Haunted Door. It is only found in Lion's Arch at Grand Piazza during Act 4 of Shadow of the Mad King, after the event, when Mad King Thorn has left. Entering this Haunted Door will teleport you into the Mystic Forge Cauldron located in Trader's Forum while the Mad King laughs at you.
