So, I have a nice house that I made out of a dungeon. I have some cool stuff, and mobs don't come in to "visit".

It's a nice base, but being holed up in a,erm...HOLE isn't really "fun". Sooo, I just usually wander through the wilderness, and sometimes get a "pet".

Well, these are some fun ideas for pet pens:

A.Wilderness Pens:
I built these originally on my SMP world, but started to make more in SSP worlds. These are around 4x4,and at the middle have a stream which goes across the pen with a lilly pad on the source. This is so your pet should take a "sip" from the stream. Also make the floor of grass and optionally put flowers on it.

B.Cave Pens:
These are new, and basically are 4x4, and have a stone floor. Also, ore could be placed on the floor/walls.
Pretty simple.

C.Nether Pens:
Only do this if you have a zombie pigman for a pet. Make it 4x4, and have netherrack /soul sand/netherbrick everywhere. Also if you want, instead of the water stream, have lava.

Sorry it's so short, should be added on soon!
