This is a simple mod I came up with one night in frustration while programming another one. I'd like to say I made it for my 6 year old daughter, but I'm not going to lie. I'm 35 and I still find fart sounds hilarious. This mod adds two new cow and chicken mobs that, well, fart ambiently as well as when hit. You also can construct a whoopie cushion and harvest beans to make a Can O Beans. I'll let you guess what those do for you. :) Enjoy! :)
