We have lunar grotto and archives which are like lunar power invading shadow territory, but what about the oposite? i think an early game shadow boss that can only be found in the ocean would be funny. Imagine a shadow mermaid or sea witch that only spawns in a new place within the ocean, and in this place there are shadow geysers (like shadows coming from the deep trying to invade lunar territory), and in this fight you have to use special boats-plataforms that only spawn here, it could be a good ocean fight even recycling the geyser attack from the old CK. I imagine this fight like a combination of the Gorgun from enter the gungeon and the Onyxia from titan souls, with plataforms that the player needs to use like boats to attack the boss and this plataforms can be destroyed by a geyser attack from the boss(with new plataforms spawning after a while to replace the others), and the boss is not static in one place cause that's boring, instead the boss moves really slow when on the surface and when she is hiding under the water during some attacks she moves fast like a serpent. I had this idea cause i think all the ocean bosses right now are boring as hell, and im talking about the only 2 ocean bosses, the CK and the malbatross, cause you know the CC and the frostjaw are not really ocean bosses, they have their own islands and you arent using the boat mechanics to kill them so with this sea witch we could have at least 3 ocean bosses and this shadows boss can be accesible from the very start unlike CK and Malbatross.
