Fantasy dimension: Purple Planet

What if there was a dimension called the purple planet and maybe additions to the overworld, it would have allot of differences, Water would poison u and would be acid. New nature ideas such as purple grass and leaves and different overworld block physics: sand makes u slower, lava heals u dirt falls and makes u faster etc. New enemys/ monsters: a purple creeper that when it explodes, it explodes into either arrows or knockback, a giant white spider that helps u kinda like a wolf but during night it kills u and cant be tamed. a flying blanket that lets u mount it but if you hold a weapon near it or on it it will knock u off and hurt u. a brick zombie that is very slow but is invincible and does 4 hearts at most with diamond armor. a skeleton with a fishing rod that reels u to it and hurts u but it can be cut with a sword. a witch that runs fast but doesnt hurt u and teleports away from arrows but if killed it could drop up to 4 diamonds, 12 emeralds, 11 gold, 11 iron and other drops such as sticks, leather, wood, stone, plastic (new material) and redstone. a camoflauge grass, stone or snow (kinda like an octorok from botw for u zelda fans) monster that grabs onto u and gives u mining fatigue and blindness for 10 seconds while it dissapeare forever but if u can kill one or dodge it will drop 6 levels of xp and a block that it was hiding in.
