In dungeons you can find mystery egg (rare), from it will hatch friendly mob, who will grow up, and fight on your side, u can equip him with armor and weapons (maybe iron/gold/diamond... claws?) also he can level up, and get his special abilities, if you click on him(right click) without anything in your hand you will open his inventory(skills, equipment, and other) You can have Only one guardian creature
Maybe it can be creature from ender dragon's egg?
