more animal variants and behavioral updates

I think there should be biome dependent variants for mobs like the goat, the camel and the phantom and animals like the polar bear need a behavioral update like making them tamable or at least breedable and the squid needs an update like making them breedable and mobs like the chicken, cow, pig, goat, parrot, polar bear need an animation update and mob variants like the grizzly bear, and fennec fox, and red panda, meerkat, ostrich, and vulture would be a great addition to the game as well.
