Mob Idea: Shroom: for a potential cave update

A small neutral mob that spawns in caves, mushroom fields, dark forest, taiga, mountains below snow level, and nether crimson forest biomes. It only spawns at lower light levels. It has a thick, roughly block sized red and purple-spotted cap with a thick smaller brown body, and stands about .75 blocks high. It has 3 stubby legs and glowing yellow eyes all around its body. It moves slowly compared with other mobs. It has a chance to convert grass, dirt, and podzol into mycellium. If it's attacked by the player, it releases a puff of pollen in a 3 blocks radius 2 blocks high that causes blindness, nausea, slowness II, weakness, and poison for about :10, :3, :50, :20, and :20 seconds respectively to all mobs in range. It can be tamed with red mushrooms much like a wolf and will use its pollen attack on any mob the player hits (reduced to 1 block by 2 block high area directly in front of it, with a reduction to 5 (still 3 for nausea) seconds on each effect). When tamed, it can move as fast as the player when following and can sit, and led and tied with leads. It has 10 hearts of health and can be healed with brown or red mushrooms, or with mushroom stew. Hostile mobs are only aggressive towards tamed Shrooms.
