The glowing mob in the cave

A glow worm in a cave that dangles like a vine but doesn’t grow can be milked. After it is milked ,which kills it, it turns into the milk in your bucket, a string and a slime ball. Milking 4 fills a bucket, which can be put in a cauldron and you can use the glow milk cauldron to die your armor to where it glows in caves like a torch. Just like dying leather you can dunk any armor in the glow milk but the chance of successful bonding of the glow lessens with better quality armor. (Ex. Leather 90-95% chance of bonding, diamond 40-50% chance of bonding and so on). Using sheers the worms can be moved into your inventory. They can be placed in a 4 block tall dark space on the ceiling which has to be made of stone. They range in hanging between one and two blocks down. They multiply like mushrooms, but in darkness, so it takes time and patience.
