Elephants and Elephant Armor

Elephants are a new animal in the overworld that spawn in savannas. They are a little smaller than a ghast but bigger than a ravager. They are a Neutral mob with a lot of health, no knockback can be dealt to them. They have 33.3% chance of dropping Elephant Skin of quantities of 1-5 and a 100% of dropping Elephant Bone of quantities of 1-3. Elephant Bones can be turned into 9 Bone Meal or can be put in a Brewing Stand with a Awkward Potion to make a Potion of Knockback Resistance which of course can be made into a Potion of Knockback Resistance II with Glowstone Dust and a Potion of Knockback Resistance that lasts 8 minutes with Redstone Dust. Finally the Elephant Skin can be mixed with leather armor in a Smithing Table to make Elephant Armor. Elephant Armor is to heavy to stay on top of Powdered Snow but it is able to keep you warm in Powdered Snow so you don't freeze in it. Elephant armor is as strong as iron but has crazy Armor toughness and Knockback Resistance.

This idea gives more use for leather armor, a good potion for PVPer's, a armor to put between iron and diamond, and a animal that makes savannas better.
