The sloth

I think you should add a sloth that spawns naturally in jungle biomes, mainly on trees or vines but they have a chance to spawn on the ground. By feeding the sloths apples, or leaf blocks you can tame them. Once tamed, you can click on them and they will strap themselves onto the players back granting 10 extra inventory slots, but the sloth’s slots cannot hold shulkers, ender chests, or bundles. The sloth can also automatically replant crops, but for every replant the sloth consumes 2 of the seeds (or crop in the case of carrots or potatoes). I think this would be a very good addition to the game and I for one know it would be features like these that would make Minecraft a game I would play more often
