A while back I commissioned KristinF to do a sequence called Goo Girl Genesis, in which a human woman was transformed — via mad science, naturally — into a a living gel or goo in a female shape. I was playing with a trope known as the “goo girl” or “slime girl.” Since I have a healthy curiosity abot the weird, I naturally wondered whether there were any other examples of this sort of narrative out there. Well, if it can be found out there is a man who can find it out, and that’s Bacchus at ErosBlog with his unique, human-driven Rule 34 searches. For a very modest commission I was able to get the following lengthy report, which I have made into a post with a little bit of editing and illustration and present for your perusal and enjoyment. Bacchus’s original text (except where hyperlinked) is in red, and my occasional glosses are in black.

You asked for a full treatment on the topic of human women being transformed into slime creatures or “goo girls”, providing one example of your own:

As you already know, this sort of thing is not extremely common. I was not able to come up with any organized communities of fans of this particular transformation. However, the “goo girl” and “slime girl” communities more broadly are very large and searches on these terms (plus “transformation”) have been somewhat useful. Below are some resources for those communities; these links are likely to be fruitful places for ongoing search and monitoring, and were among the starting points for finding the specific goo-girl transformation links listed later in this report:

I looked hard for, but did not find, fanfic or erotic stories with slime girl transformation elements. It’s out there; I just failed to find it I think. Nor did I have much success finding relevant movies or television.

Not porn, but there appears to have been a sequence in The Daring New Adventures Of Supergirl (##1-3) in which a villain named “Decay” gets turned into a brown oozing slime villain by psionic attack, before eventually being turned back again. Haven’t hunted down the comics, but you can see him in slime form on the cover of #3.

Not porn, but there’s an episode of the Power Rangers TV show that seems to feature people being transformed into slime by a potion.

Apparently there is a horror movie called Slime City in which a man eats the wrong thing and is transformed into slime, which process can be reversed (or slowed) when he murders people.
