His genitals strangely return to their original skin color

The scientist tried desperately to pull the slime off of him, but the seal had already become nonexistent - it was inexorably fused to his skin. He was too late.

But in a strange turn of events, he saw his skin slowly shifting back to its original hue - as if a chameleon were coming out of hiding. Too awed for words, he could only watch in silence at this unbelievable sight.

Unfortunately, that only lasted for so long before a sharp rapping came from the laboratory door. Despite his racing thoughts, a man of his position was not the one to be caught exposing himself in a place like this - he quickly got himself together and went to go answer the door, but his mind was elsewhere. What the hell had just happened? Did it just dissolve and disappear forever? Is it somewhere inside his body, lying dormant?
