Yeah that only works well when your players don’t know them… Or you modify them.
Players: “What does it look like?”
DM: “It’s entirely unimaginable. I couldn’t possibly describe it.”
"It’s different every time you look straight at it, but the details are always viscerally repulsive. Fractal insect limbs and cracked teeth and spores all co-mingling in wet, stretching flesh. Its outline is sharp and fluid but your left and right eye can’t agree on the details. The edges of it feel too far away, and the middle won’t focus unless you look at your own nose. When you do, all its eyes glance there as well. "
“Pieces continuously break away and reattach to the whole. Some shrink away into nowhere while giving the impression of getting closer. Others boil into existence and join themselves together. All give the sense that they belong to a single being, but you cannot find the connections between them. You feel heat radiating from the closeness of its flesh, from a direction with which you are not familiar.”
