The Cursed Nightroot is an interesting idea, kind of like the veggie equivalent of the Phosphor Slime. Also, the Shadow Slime spawning deep underground would make for an elusive slime.

What would be cool (pun intended) is a puzzle with ice that blocks your way into the caves, in which you need to heat the ice up, somewhat, but not fully, similar to the puzzles found in the Glass Desert. I don't know how it would work exactly, but that's something I'll leave to you (if you want to use the idea, that is).
