You thought hard about it, and since your girlfriend would choose a superheroine as a cosplay for the convention, so could you as you selected that body type before anything else could happen. You select the heroine option, and began to wonder what would happen, but then saw the screen give you an option.
The question was the same one that was given to your girlfriend before she became Wolf-Girl, and you suddenly got distracted by her new body, that you couldn't decide. Just then to break your trance, you heard Dr. Terrific tap on the machine, while you saw her neck hanging with her stretching powers, while holding onto the clipboard. "Would you like to hurry up, child?" Dr. Terrific asks. "There are other people at this convention who would like to use this machine as well, you know."
