You chase after the big and buff bull man. When he sees you, he turns around.
"May I help you?" he asks.
"How can I get my body back? I really don't want to be a werewolf, especially a fat one! You look like you know. Can you please help me?"
His face tells you that he's thinking. Then he says: "Okay. I"ll do you a favor. We'll exchange forms because you have a better chance of finding as a minotaur."
"Thank you...." you say.
"But," he says right away, "make sure you find him before sunrise. Or else, we'll both be stuck in these forms forever."
You nod, agreeing to everything he said. You figured that if this is the only way you can get your body back, you'll take the risk of being a huge minotaur forever.
"Okay, look into my eyes." the minotaur said. You look into his eyes, and you change in a different way, not like with the werewolf. No, this time, you transform slowly. You feel your huge belly retracting, changing your body into a more fit and muscular form. Your fur changes too, turning from grey to greyish black. You see the minotaur getting smaller and smaller, as he is also changing into the werewolf you once were. You feel your paws turning into huge hands, powerful enough to kill a person and break a wall. You see your legs shift to a more bovine form, and you also see your feet changing into hooves, bull hooves. You feel your chest growing larger and larger, your shoulders becoming broad and strong. You suddenly see you have a reasonable six pack, which makes you somehow very pleased. You see your tail, now a bull's tail, swishing back and forth.
The last thing to change was your head. In agonizing pain, you feel your werewolf muzzle becoming shorter and just bovine enough so it looks like a minotaur's. Your eyes still remained human. But your ears flop down and you feel two big and white horns coming out of your head.
After a few seconds, you breathe. You see the minotaur-turned-into-werewolf standing in front of you.
You realize that you are taller than him now, hovering at 7 ft. You flex your muscles, your biceps, your triceps. You were so busy flexing you didn't realize you had a lioncloth covering your genitals.
"Feels good, doesn't it?" the once-minotaur-now-werewolf said.
"Yeah, it does." you answered, admiring the deep qualities of your voice.
"Well, don't get too comfortable. You only have until sunrise to get him. If you do, meet me at the souvenier store."
You agree, and you start looking for the once-werewolf-now-you in the dark zoo on Halloween night.
