Many years people quit caring about things such as poaching and the laws of endangered animals and started killing them. Years after the animals be it mammal, reptilian, avian, amphibian, aquarian, or even insect, humans being the only ones left, a scientist discovered a way to bring them back, so to speak. He had collected each and every creature's DNA, even those that were extinct since before the stone age. But there is one problem. Cloning is against international law. So one would have to use human test subjects. The professor has been kidnapping college kids to do experiments. He held many kinds of animal DNA, and chemically engineered them to be three types. Biped, quadruped and tauren. He began walking up to his first subject... you. The sub-types of the DNA were male, female and hermaphrodite. He stood six foot. Your gender doesn't matter, nor does what your race is, and it certainly doesn't matter your height or sexual preference. That will all change. Like many before you he injects you with the syringe. The stuff is contagious, thus why the place is near escape proof. When he sets it down he drops you into a pin below to leave you to your own devices.
