Cthulhu Boss and New Items

So the Nether,End have a boss,but the overworld doesnt have one (not the wither) so its cthulhu ,So the way to summon him is get a enchanted trident with all enchantments so like loyalty channeling ... and you get the trident on a fishing pole but the fishing pole aint a normal one its made with 3 blaze rods and two string oh yes this is a idea aswell for fishing in the nether,so you fish for a little bit and cthulhu and yes you can do this in biomes:snow,nether,end?,forest,savanna,mushroom biome but cthulhu has a diffrent skin but in nether is HARD MODE so ya ,if you asking for attacks i dont know and the final new items and drops.THE DROPS:Cthulhus toy and you find a squid you can turn it to a pet,golden apples,diamonds.New items:Trident on a Stick,Cthulhu toy. So yeah a cool idea so if you like it  idk like it?
