I know there are already videos out there showing this, but I just wanted to show my experience and it was "sick". We were just curious and trying to get in the little dungeon/jail. It's in the lower part of the maze and it happens when you die to of the monsters. Anyway, one of the people I was with managed to get in the dungeon and he found out that there's a little secret hole that leads out into the rest of the map and it lets you stay tiny. Sadly you can't get out of the basement while still tiny. We tried. it brought us back to normal size right when we tried to go to city. Anyway, this was absolutely crazy, go try it out for yourself if you haven't already.
