He drinks it

Santiago after reading the sign he wanted to drink some of the liquid. "Man I wanted to know what this taste like" said Santiago "Uh sweetie I don't think it would be a good idea to drink that I mean the sign says what it says" said Scarlet as she feared for her boyfriend drinking the liquid formula, "oh nonsense Scarlet honey, I bet this Liquid can't do a damn think to me" said Santiago with confident. There his crush Scarlet feared again at what he was going to do.

"Ok bottom's up" said Santiago as he then drank down the Liquid to the surprise of his crush Scarlet.

Then as Santiago had drank the liquid he then, out of nowhere started to turn into an animal as he had shrunken out of his clothes to the shock of his crush Scarlet.
