I suppose it'd be trivial with progs_dump, but this is more of a lost media quest, with a dash of making sure I'm not dreaming up a false memory. I remember seeing a low-res image of a blue chthon in a pool beneath a blue sky, surrounded by sand-colored brushwork.

Oh and speaking of dreams, one day when I was a kid I dreamed of a Quake level where a monster that looked like a cross between Chthon and a shambler emerged from a pool of murky brown water with very little room to move around it. (Might have been influenced by that one ogre in e1m4.)

Honestly, there should be a Chthon variant for every liquid texture in the vanilla wads
