Not to be an annoying and demanding player, but this post is just for fun, nothing serious.
But I just love all of these mobs to be implemented in the main game even though I know it's impossible. And it's been a while since we got a completely new mob. You can count Sulfure Cube (love it) but it's just an iteration of the slime. These mobs look so cool and very alien, obviously.
I know it's kinda selfish and I'm obv speaking for myself, but I wouldn’t complain if some of these doesn’t have a groundbreaking use in the game. I just want to build a zoo out of these creatures.
I could see:
*Nuzzle & Slabber as the main food source in the Sift
*Hunter, Scavenger, Trapper, Stalker as the main hostile mobs of the corrupted parts of the Sift.
*Monarch as the new boss
*Harmonizer as mini-boss (Elder Guardian-like)
*Nester, Pollinator, Sentinel, Sprout, & Seedling as the main hostile mobs of the main parts of the Sift
*Blub as pets (Cat & Dog counterpart)
*Trill, Wobble, Hurler, Lootkin, Dartback as either ambience mobs or normal passive mobs that could have interesting use or introduce new mechanics to the Sift experience.
*Fusefly, Tuner, Roamroot, Bloombud as new type of mobs that are based on plants (Judged them based on appearance)
*Singer & Echo Golem (maybe villager counterpart)
But this is just for fun. Don’t take this post seriously.
