Ghast like mobs or any kind for the soul sand valley

The soul sand valley is a very nice addition, however it does kind of feel barren. Yes, I understand that it is supposed to be barren, but i feel like there should be a biome specific mob for the soul sand valley. I’ve seen ideas such as worms and crawlers which do fit well with the biome. However I think that there should be a ghast related mob. One that could be floating low atmosphere or could be floating right above the ground. I do not have any specifics for what it does or how it does it. It could maybe charge at you, taking your slowness on the soul sand as an advantage to hit you. Or it could keep its distance and shoot less explosive projectiles at you. I will leave the decisions to the minecraft staff to decide
