You are a scientist working with a genetic engineering facility, you've been working with a male coworker named Ben, recently you were given actual raptor DNA, and so, you made up a serum that turns anyone into an anthropormophic raptor, but you needed a test subject, when Ben was distracted, you poured the serum into his coffee and waited, once he drinked the coffee, the transformation started to take place, but it seems you made a miscalculation and transformed him into a 12ft tall female raptor-taur, after the confusion wore off, she turned to look at you.

Ben: dude! Did you seriously had to do this to me? I hope you have a serum reversing this because i will put to use my new claws
