The Demolition "artist" as they call themselves. A nutter, yes but fun because of their quirks.
From Tzh Cyoa
You go over to John's room and go in, to find him countinously making explosion noises. Was this such a good idea? Do you
Go in and take part in his explosive noises
Go in and start talking to him
Go in and stand there, until he notices you
Do something else
