There is a combination after defeating Nails o< leary. I havent been here in a long time so i forgot the combination. But there are cheats you can find i think you can find on the site or wizard101central!
Oh and after you defeat Nails O' leary, Look up at the top of the door entrance and you'll find the combination,
PS. I said fireguts. My bad! thats Katziens lab. 8)
