The Spitting Cobra And The Tree Snake, Desert Snake Too? (Also a New Biome)

Dear Mojang, I have had an idea for the jungle biome. Right Now the Jungle Biome isnt very dangerous and it is quite easy to travel on the trees so you could add the Tree Snake, a snake that inflicts the poison effect. It could come in many variants to blend in with the trees like green, brown, and the occasional pink? The Spitting Cobra would make the Jungle Floor a lot more dangerous as it does 5 damage (without armour) and the spitting deals some damage on hitting the player and poison 2 for 15 seconds. With that I also put out there a new biome, the subtropical desert. It will lack water and cacti and spawns husks more frequently, there should also be the desert snake. It lives in small holes in the ground and pops out and attack player that walk by. The desert could be expansive, going on for a few hundred (or thousand) blocks in every direction. But desert temples could spawn more often. Anyway those are my ideas. Hope you see them! :)
