Coming in 2022 to The Wild update mob allay looks like a little light blue fairy with bat wings. If you give it a cookie, it will find nearby dropped items of the same type. However, it won’t duplicate that cookie or rifle through chests for it – it’s purely about picking up that item when it’s dropped on the overworld. The allay will then drop the collected items near a note block, evidently because it loves to dance. Minecraft game cursor with Allay and a Cookie.
