Unique Sculk/Deep Dark Dimension

Entrance: To enter this dimension, you should need something from The End dimension because to get to the Nether you need to get something from the Overworld to get to The End you need something from the Nether so you should something from The End to get to the Sculk dimension. For example, dragons' breath (dragons' breath is basically useless) Also the portal will be in the Ancient City.

Theme: I think the Sculk dimension should be like a giant organism, with each biome being based off of an organ some made up some real. So, some entities and blocks should be like cells and proteins. Example block: Sculk Jaws should be added because they are similar to a type of plant cell that is like a mouth. Example entity: Some sort of fly mob that is like a search light that fly looking for invaders.

Blocks: This dimension should have some new blocks, like a "cancer cell" block that would spawn in blobs all around the dimension. Or a new fluid "sculk blood" the sculk blood is a bad name but it would spawn all around the dimension (Especially the heart biome).

Entities: There should be a new sculk turtle that would be like a living sculk sensor it would be peaceful but would warn others. Another entity is a boss fight because each dimension has a boss fight this should be "The Catalyst" it should be like a big lizard that can climb on walls maybe.

Items: I don't have many ideas for this but there should be an item reward for defeating "The Catalyst" IDon'tHaveEnoughCharactersToWriteMore :(
