What does a Kalabon devil look like?

[Yari]

I want to have some kalabon devils in a game (coz of the hag connection) and I like to sculpt miniatures, however I can't seem to find any images of the critters anywhere apart from the one with a human body with deformed grinning head.
Is that even a kalabon or a possessed human or something.

I'd love to get some other descriptions or pictures to work with if anyone can help?

Because it's mislabled in the art gallery. Here the critter is:

Ah, cheers but that was the image I had. I had hoped there was more images around, that one seems to be a human with Kalabon attached to its head, facehugger style.
Don't look much like the description, although I guess I can deduce it looks a bit like a grinning jellyfish :/ Would love it if could find a pic of Kalabons when they are together in a colony.
