You woke up with a bag over your head in a dark room confused. The last thing you remember was going to a zoo."What's going on!? Where am I!?" You yelled
"It's awake," you heard a voice say
"So what? It's not like it can do much, especially since it's nude." Another voice said
"What?!" You yelled, but then were hit in the gut.
"Shut up! Nobody wants to hear whatever you're trying to say. Nobody can understand you animal types anyways." The original voice said
"Cut it out you two, this one is worth more than either of you. Take the bag off briefly, let it be a surprise to whoever this thing was." A third voice said
Suddenly the bag was pulled off and you saw two men wearing protective armor, and helmets that hid their faces. Then there was a third person who was a man, he was bald, and he was wearing a lab coat.
"Greetings, your former identity doesn't matter now, you may develop a new name in time. If you even understand my words right now I would like you to know something, I am only in charge of acquiring new animals. Those at the zoo will treat you far differently than I, but these men are insolent, and insubordinate. Do not let their violence change anything about what you think of me, or anyone trying to get close to you. You are very special, you are our first humanoid animal. Know this, your humanity is behind you now, so I encourage you to accept your changes, goodbye." The man said then suddenly you felt a needle in your side, and you passed out unconscious seconds later.
When you woke up you saw people, but they were on the other side of a glass pane. You looked around and you saw animals around you. You were going to yell, but you remembered what that man said about you and remained quiet. You then looked at your hand and you stared at it, you weren't human anymore, in fact your hand looked like a version of paw/claw/hoove/leg but you had thumbs on both hands. You looked at the walls of the exhibit but the walls were too high to jump to. You looked down at your body again, and again you saw that you had become a humanoid......
