He got the slime from the black market after he had learned about it online. Most people he asked just scuffed as if such a thing was ludicrous... but he knew it was real--the video quality matched the parts most claimed were doctored. The shakiness of the videos would have made it near impossible to animate in with todays best tech let alone with what the 3rd world country farmers had at their disposal. So he did his research and dabbled.

He found some less aggressive slime and went at it mixing it in the tub as soon as he got the 3 part mix required. If Nicolas Flamel learned his craft well enough and combined it with his natural unmatchable talent in order to make a sorcerer's stone, then whoever made this slime must've been an equal in terms of alchemy and magic.

But for this boy, it has become nothing more than a fun toy. Will he go on more adventures with more-alive slime? Who knows? All he had with him on his trip to where this stuff is found was a small camera that didn't record audio. And so, here is the video evidence of his long journey to find the living slime. What a fucking freak. What a cock. Envy him.
