New Mob, Shroom Sloth

A new mob that spawns in all the dimensions and has multiple different forms. It would be called a Shroom Sloth. It would be a medium-sized, sloth-like creature with various mushrooms growing on its back. It would be native to multiple places in all 3 dimensions. There would be red and brown variants in the overworld, warped and crimson variants in the nether, and a chorus variant in the end. The nether variants would also have shroomlite growing on its back as well as mushrooms. The overworld variants would spawn frequently in Mushroom Fields biomes attached to giant mushrooms and rarely in Roofed Forests biomes. The nether variants would of course spawn in the Crimson and Warped Forests, and the end variant would spawn attached to chorus plants with a new type of mushroom called Chorus Shrooms. They would not be tameable, but they would be an easy source of mushrooms because they usually stay in one spot. Over time, the sloths would grow moss on their backs if they stay still for long enough. You would also be able to shear the moss off of them. I don't have any idea what a model would look like, but I hope if someone sees this and is good at making models, they will share what they think it should look like.
