    Working in his lab, making sure he makes this invention perfect. He seemed to have gotten no sleep for the past couple of days. His determination is the thing keeping him up. Welding and screwing stuff in, while hooking up wires and lights to his invention...he then heard a knock at his door. It was very late, he didn't know who would be out so late at night...even Sonic wouldn't be out this late. He walked up to the door and opened it to see you.

    "...Hello, who are you?"
