Step 2: get about 350% speed. (No, I'm not kidding. These suckers are FAST! Luckily 350% is about enough.)
Step 3: make it aggro ya, and trap it in the square, but make sure to stick a large bear trap in the trap first!after its stuck, put wall 4
Step 4: get a good longneck or crossbow and start tranqing!after he's down (or she) stuff him (or her) fulla meat!
Step 6: get a saddle and have fun!
