Which terrain is this?

I remeber when Furion went underground for the druids of the claw. It was kinda like a cavern place, with a blueish-purplish(im color blind) tint to the ground. Could someone tell em which tileset/terrain that was?

It might have been a custom tileset (mix and match the existing tiles, it's under advanced/modify tileset)

I think that was the Underground tileset. It's the icy cavern right?

I was thinking that too, but I'm pretty sure I remember some snow in that map, and the underground tileset doesn't have anything like that.

It's either a mixed tileset or custom made tileset.
