I have been working on a new map for a while now called Googlie Spawns. ‘Googlie’ is the word Stampy uses when talking about hostile mobs.

The rooms are leveled from easiest to hardest (I tried to sort it that way, at least) and so far I have built six rooms.
I’m not going to take a picture of each room, but here are some photos I took of some of the rooms:
