>>101337675I was looking for that comic the other day and came across this explanation on reddit: I could be mistaken, but i believe this is a comic about endochondral ossification. Skeleton jelly is essentially a chondrocyte (cartilage cell) which hypertrophies (drinks the well) and dies (gets eaten). He then cacifies (squirxical jelly) and then drips into ultraviolet city, which looks suspiciously like the trabeculae of ossified bone. I'm pretty sure it's not all a coincidence, it made me chuckle.
