Trap door

Magnet holes added to work with my other remixes. Can also work on a corner tile with a corner wall, however, it will be very hard to open just by hand. If you're using the newer magnet bases that have a space in the middle, you can even fill the area for some added flavor (a small picture of stairs or something) If this is on the second floor going down to a lower lever then I'm sure you can find ways to line up some ladders or stairs under it. Magnetic stairs are also on my to-do list!
