New creatures and a new biome inside the game

[Rodimus]

How about adding turtles, eagles,snakes and a desert biome inside the game?

Like 4 turtles spawn in lakes and 1 turtle spawning in a riverside.
Eagles would spawn in mountains and where there is alot of pine trees.
Snakes, would always spawn everywhere. But there would be more snakes in forest tiles and in lakes.
