Mob idea: Glimmer Orb

So my idea would be the Glimmer Orb. It is a friendly Mob that emits light in the dark, helping the player navigate in the dark. Where does it spawn: Lush Caves and/or Mushroom islands New items: Glimmer Crystals: These are green ish crystals which are glowing and they can be crafted with an amethyst shard and glimmer dust. Glimmerweave cloth: This item can be crafted with glimmer dust and Wool/Strings and it could be used to craft decorative items banners and/or even clothing Hope you like my idea!! :)
