You can observe change in the appearance of some mobs keeping the vanilla feel. Most of the modified mobs are old or less detailed than the new mobs in new updates. Some are not consistent like the chicken that looks like a duck or the baby cow with horns. If you have any idea to change another passive mob let me know in the comments. Hope you enjoy!
