i have a idea for a 1.13 update

i have a idea for a 1.13 update i have been working on a 1.13 update mod for 2 month and i made alot of good mobs structures and even a new biome the toxic waste land biome 5 new mods the sculk hunter a wolf like mob that guards the the way in to the ancient city attacks a shockwave and a dash attack drops a block of sculk 100hp next the ancient golem a golem you can find in one of the new structures the town ruins you can tame them with redstone they can help the player make farms help the player defeat mobs next is the scorpion a beast that spawns in the dessert and it will attack the player if they get close attacks summons dust tornadoes and a poisonness stinger they drop 1 to 3 diamonds they have 125 hp

the other two do not have names yet ones a chameleon and a jellyfish

new structures the town ruins is ruins of a ancient town spawns in the plains biome next the crashed end city ship spawns in the end city

and swamp villages and jungle villages

and the toxic wast land biome a biome that is very dangerous puddles of acid spawn and if you touch the acid you will be put on fire and thats it i hope this is a good idea for 1.13

oh and the name of the update is lost ruins update
