Minecraft, Animal Generator

OK, this is quite funny. But it works !! For those of you who are lazy to go hunt some animals, I have created this animal farm.
 
 Firstly, find yourself a nice flat piece of land.

  Next. build a nice 2 or 3 block high wall around it and make sure you have some way of getting in and out. And make sure you light it up.

Then, wait for nightfall, and this is the time, when the fun begins. go explore and this is how it should look like.

I hope you like it, and enjoy your meal ! :)
