Accurate mobs for each biome

I think the game n biomes feel empty since there’s not really any mobs and it’s kind of silly seeing pigs and cows in the dessert, we should be seeing snakes, vultures, camels, kangaroos. Same goes for other biomes like the ocean, we should get sharks, whales. We should get lions, gazelles, elephants you can ride(probably tame), giraffes. Some other ones can be alligators for the swamp. It’s about time we get some new mobs, especially now that we have a new world generation update and you guys are working on the wild update, it only makes sense
