Sticking with the pre-alpha Minecraft thing and 'him' (The weird thing that likes to mess with me) we have the story of how I built my first slime farm....The epic way.
I decide that I should make something creative and epic then realizing that I can mess up putting down two blocks I decide to make a slime farm but since they're no mobs in pre-alpha Minecraft I have to get creative.....Very creative. I start by making a square wood frame with a glass ceiling. The door way was three blocks across and three high. I put out Protection Sponge! (Sponge that keeps my stuff from flooding by being put under the doorways and any other entrances ). Now fro the slimes....the slimes. I put out blocks of wool in the shape of slimes and named them. But soon the fun came to an end when 'he' came back and I had to leave.
The slime farm has spawned many other of my creations.
