Here's a somewhat small mansion I made. It has a few puzzles and some interesting sights, a good amount of secrets, custom backgrounds, and lots of LAVA! all compiled in one mansion of 23 rooms, it should be packed full of excitement!
toybox- I fixed the problems
Sam - I like your little mansion, but when I tried to put the backgrounds in the Screens folder, I realized that I already have backgrounds numbers 9, 10, 11.
Well, all you need to do is change the numbers at the end to 12, 13, and 14. Sorry about that, wasn't thinking. Pretty much what Mikee said. (I think...)
