You walked inside a Halloween themed elevator, and eventually opened up to a large outdoors area, occasionally having a lit up house, and gates that acted like the doors from the hotel.

Sometimes, when the 'Treaters' gave you candy, you'd get a bad one that made you feel sick, or make you lose some health (luckily a lot of bandages were nearby so it wasn't bad).

...You even had to chuck a few to the side since a few of them could explode. And before you could tell the 'Treaters' of their 'mistake', their lights would be off and they wouldn't answer.
