Introduction: Ant Farm
Hello, everyone! We are back with another episode of Minecraft Creations (I'm still young, so please don't be rude) and today I am going to show you how to build an ant farm! Don't worry, for they're only passive mobs, and don't bite. So let's get out there and start building!
Step 1: What You Need
To make the ant farm you will need the following:
Passive mob eggs (Sheep, Mooshroom, etc.)
Glowstone (not shown)
Podzol (not shown)
Any block (not shown)
Vines (not shown)
Pickaxe (if there is stone)
Not Needed (just used to corral the animals for the screenshot):
Step 2: Flat Surface
Do one of these:
1) Find a flat surface
2) Make a flat surface
3) Build on a superflat world
Step 3: First Hole
Make a 4x4x3 (length x width x depth) hole in the ground (torches can also tell you how wide, etc.) .
Step 4: Second Hole
Dig another hole that is the same size and depth like the first one. Notice that there is a two block distance in between the holes.
Step 5: Tunnels
In between the squares that you made, make a 2x2x3 hole in the center. Please ignore the slabs, I had to keep the torches in the air.
Step 6: Repeat
Repeat steps 4-5 until you have your own pattern of tunnels. An example is shown above.
Step 7: Ants
Spawn the animals in the ant farm. Now you can see them crawling about!
Step 8: Roof
Put glass on top of the tunnels. In the center, there should be a 2x2 hole, so you can make more ants. Make another hole on each dead end (should be at least one).
Step 9: Towers
Make a tower on each dead end hole. The tower should be four blocks tall. Add a fifth layer with podzol/coarse dirt.
Step 10: Top Layer, Glass Walls
Once you have added podzol to both towers, make a podzol surface . Once the surface is done, add walls of glass, 3 blocks tall .
Step 11: Glowstone Lanterns and Glowstone Stairs
Meanwhile, under the podzol, it is getting dark, so add some lanterns to lighten the first layer . Add stairs by using glowstone in a spiral shape, inside the tower [2-4].
Step 12: Watchtower
Use any block (I used coal) and create a two-layered tower you can climb to view your ant farm. (The glowstones are supposed to be holes) . Add fence around each layer  and glowstone on each corner of the fence . Now add vines on the pole (for climbing) and you're done!
