Description
-- OPTIFINE / ENTITY MODEL FEATURES AND ENTITY TEXTURE FEATURES IS REQUIRED --
This pack replaces the minecraft Cow with Deer! specifically the Red Deer with both male and female variants, though don't act surprised if you can still do ungodly things to a male deer cuz yeah it is just a reskinned cow:
Male Deer
Female deer 
and at last, the Mooshroom is replaced by the Mycervium (thanks to natalia0310 for the name)! 
This also comes with updated sounds and names, including the meat, which while it kept the same texture is now called 'Venison', enjoy!
