Desert and mesa upgrade

A new desert upgrade that adds an oasis biome, palm trees, quicksand, vultures, tumbleweeds and layered sand (like top snow but sand texture) this would make the desert biome smoother and look more natural and make it easier to traverse and more immersive. meerkats and different cactus varieties like a flowering cactus, a saguaro cactus and a shorter wider cactus and maybe make a cactus fruit, This would make the desert much more alive. This upgrade would also change desert temples to have the same above ground area but a bigger underground area that has random generation just like strongholds. The new desert temples could have new traps and rooms and could add pots that you break and drop one or two common items like arrows, gunpowder, bones, string and flint. The temple could have suspicious sand and a single treasure room that has gold and other good items. With this upgrade new types of chiseled sandstone and red sandstone and that you could use pottery shards to imprint into sandstone and stone bricks. A new sand type skeleton could be added that spawns inside the underground area of desert temples the skeleton could give a debug potion effect like weakness or a new potion effect that fits the challenge of the desert temple. This upgrade would add a mesa village inside and under cliffs much like the buildings in mesa verde. Another idea is to add a choice when making a world to remove infinite water. This upgrade would make the desert much better and more interesting.
