The stranger pulled out a crowbar from his trench coat, as he spotted a glass case containing what looks like a lobster shell, but it looked like it was made of some form of ruby. While using the crowbar, the man opened the glass case, until the door to it landed open, after flipping 90 degrees, and letting him able to grab the shell.
All of a sudden, the man heard alarms go off around the room, as a giant steel door sealed the entire room shut, while at the same time, there were no windows he could escape through. Just then, blue magic fog came from the vents of the ceiling, which surrounded the room, and causing the thief to drop the shell he was going to steal. Then just as the thief inhaled some of the blue fog, he found his own hand turning red, while his fingers fused together, having them become a lobster's claw.
