Jake's Unisex Hair Palace is already in the game :)
I hope to see a Headless Homer and a Cat Marge (both from ToH XX) as available costumes for them to wear in the game. Please!
Oops, my apologies! Headless Homer came from an earlier Treehouse of Horror. But would still love to see him! Cat Marge came from the intro of Treehouse of Horror XX, when she opened the door for the costumed monsters.
Well I don't know about headless homer but the end of the campfire quest might be foreshadowing cat Marge in this event
Wow, someone really botched this one up. At the end of the campfire quest, Marge was going to be a cat for Halloween. But going through Luann's quest (and showed throughout Act 2), Marge went as a witch that she even admitted to in game conversation. Homer got a new costume, so I take consolation there, and The programmers couldn't remember what Marge was going as from one act to the next.
