Bison!

(See the Teepees! Post for additional info) Bison are a bulkier passive mob that can be strictly found in the plains biomes. They spawn in small "herds" which consist of two adults and a calf. These herds will spawn in close proximity to each other. If you get too close to these mobs. One may become hostile and charge you in order to defend their young. Their gore attack can deal devastating damage to the player, which forces them to be careful when trying to slay them. When killed, Bison mobs drop extra amounts of beef and leather. Their leather can be used to craft a teepee. Similarly to cows, bison can be breeded by using wheat and can also be milked. The size of the bison mob is the same as the ravager.
