More animals in Minecraft!

Now I know we have a lot of mobs and animals in the game already, but I think Minecraft should start focusing on animals that would get the attention of people. An example could be reptiles! As a reptile owner myself, I think Minecraft needs to improve its reptile game further! Now I know there are sea turtles... I can't even think do the reptiles in the game. Now there is probably more that I can't think of, but it would be amazing if they could add lizards, more species of turtles, tortoises, snakes, salamanders, crocodilians, and so on! Other than that it would be amazing to see the sky having a bit of activity too, now I know there are parrots already but having other colorful and even predatory birds flying over the sky would be amazing! If we go back to land, we could have more marsupials like wallabies, kangaroos, koalas, sugar gliders and I can't name due to my knowledge. I am no one to lecture Mojang on their animal additions but it would be amazing to see these types of animals and even more come into the game! And I haven't even talked about the oceans yet! It would be very fun to have these animals interact with the game with small details. I hope I could get the message across.
