Zombie wolves, Sledges and Sledge jockeys !

This is one of my earlier concept from the mounts of mayhem drop, but updated for this drop !

Zombie wolves would only spawn attached to a sledge when a sledge jockey spawns. Like the zombie nautilus, zombie wolves will become neutral when the rider is killed, unless attacked. Can be tamed with bones just like normal wolves, but can't be bred. They would have 8 hearts of health and drop rotten flesh on death. Unfortunately, no zombie wolf variants, because i think its a bit too much, and they're zombies anyways !

Now the Sledge ! Crafted with 4 wood planks of any type and 2 iron ingots in a crafting table (1 plank in top left or right corner, 3 planks in the middle row, and an iron ingot in both bottom left and right corner). To balance it with the boat, the ice feature from boats would be removed to be used by the sledge instead. The sledge can climb 1.1 block tall (avoid being stuck on path blocks) and would work better on snow blocks, snow layers and on any type of ice. 2 wolves could be attached to it, making it go faster.

Sledge jockeys: a frostbite would throw ice balls at you from the sledge while the 2 zombie wolves attached to the sledge charge at you to attack you ! A pretty deadly combo if you ask me !
