this mob based on the great hunger is usually passive but will attack if you hit it or if you're wearing diamond armour. if it's reeealy hungry, it will attack you if you're wearing netherite armour because you upgrade diamond to get it. if it's not mad at you it's possible to tame it with anything made of diamond and will spit out any other material that's in the crafting recipe. like obsidian and the book in a enchanting table. after you tame it you can safely wear your netherite or diamond. if you bring it near diamonds that are out of sight it's tail will flash brighter the closer it is to them.
I accidentally said diamond eater instead of diameter and that's how this was born
