This has been bugging me since I played it the first time over a year ago. After you beat Penguin in the Iceberg Lounge, he sends you into Solomon Grundy's lair by blowing up the floor of the lounge, right? Afterwards, you are back in the Lounge, which you revisit a couple more times, and the floor is intact and there is no sign of the Grundy arena. Can anybody give me any insight to this? I've looked all over the Lounge to find a boarded up hole or something, but I can't.
