"the northern frost" a frozen zombie variant

this zombie variant seen in cold biomes like the jagged peaks or the tundra, this mob unlike the husk will not replace zombies in cold biomes but instead spawn along side them

the behavior:

the "the northern frost" will have higher health (around 25) than normal zombies and deal more damage (around 7) than normal zombies, but this zombie type will spawn less than normal ones.

the "the northern frost" will also inflict the freeze effect (the same one you get when you get stuck in powdered snow), the freeze effect will last the player either dies or switches to leather armor

once the "the northern frost" leaves any cold biome and enters a warm or temperate biome it will start taking damage and die like the snow golem

design:

when it comes to design the "the northern frost" will look like a "Zombified Yeti" and also it will be the tallest zombie ingame being taller than the husk and the withered skeleton

drops:

this zombie will drop rotten fresh, ice (sometimes) and a new mob head
