"It can change a person into any animal, but it's not random," Dr. Singer said. He looked around his lab table and then smiled when he spotted something. "Ah, there it is," he said, picking it up and showing Tom. It was a small lock of hair. "What you need to do is take something from an animal, preferably hair since it's easy to get, and drop it into the liquid. The hairs will dissolve as soon as they make contact. This adds a specific DNA to the drug. The DNA will then bond with the DNA of the subject, once ingested. The more samples of DNA used, the more the subject will become like the designated animal."
"Okay, next question. How do you know this works? Did you try it on ..."
"Animals? Yes. Come here," he said, waving Tom over. He took a tarp off of a nearby cage. Tom nearly jumped back at the sight. It was a dog, but it had antlers. "Kind of reminds me of that dog from the Grinch story. I love that book," the doctor said. "The movie was okay. But the book was better."
Tom slowly approached the cage and looked at the dog. The antlers weren't glued on or something like that. They were actually sticking out of the dog's head. And on closer examination, the dog also had hooves.
He turned around and looked at Dr. Singer, who seemed quite pleased with himself. But Tom wasn't sure what to think. Suddenly, he saw his chemistry professor as something different than his teacher and mentor. He saw him as a mad scientist who enjoyed creating monsters. More and more, Dr. Singer was resembling the fictional Dr. Moreau and Tom wasn't sure he liked that.
