i added a new room!
I call it the flood room!
Here it is:

So it's called the flood room because usually it is flooded with water... this si actually pretty common in sewers... as you never know what can come into the sewers... these rooms keeps junk away from going to the sewerwatercleaner room, and when a month has passed they can simply remove the water "flooding" in the room and remove the trash and start the "flooding" again?
But what is really hiding in this "flooding" room?
