[1.2.230] Black Magician rears his head

The monsters very much remind me of the El Nath yetis.. possible connection?

Yes, there is a yeti in the background of the Dark Magician picture.

There is also a bigger form of these monsters.

Which looks like a Yeti with a plant growing out of its head.

I'm expecting to see more monsters that look like this. Probably a Yeti with stringy hair and a flower out of its head, like the shadow you see in the Background of this picture:
