Is there anyone who is interested in being a special attack ninja slug?
The costume is an extremely simple hoody cape that you can put on over whatever you are wearing and take off after the attack. It shouldn't muss up a real cosplay costume too much. It might even be funnier if people could recognize a character under the hood.
For the attack, it would involve any ninja moves you can think of using your elbows or shoulders instead of your hands. Or wiggling around the victim until they are paralized by your "slime".
Anyone interested?
