Primordial Bloom

A new major boss for the game, not a miniboss like elder guardian or evoker, but an actual boss with health bar and a long fight. it's found in a rare structure spawned in underground lush caves, the structure is a large open space with a giant bulb in the middle and 4 smaller bulbs on the 4 sides of it, the bigger bulb is the primordial bloom which is found asleep intil awaken, to awake it the 4 smaller bulbs have to be set on fire, awaking the bloom and starting the fight, the bloom can only be damaged when it's petals are open, it attacks by shooting seeds above that will become new hostile mobs to protect the bloom, and the bloom will eventually open itself explosing it's interior where it extend tentacles to grab players and slowly drag them to it's interior, the player can destroy the tentacles to avoid getting dragged, once getting dragged the player will be swallowed and will take damage over time until released, to be released the player must continuosly attack the flower from inside, once reaching half health the bloom will start moving around the arena and chasing down players with it's exposed carnivore plant mouth and shooting a barrage of projectiles, i hope this doesn't get much like terraria's plantera
