Who: Carl Schliff
Note: Character is a postman roaming around the Royal Flush Plaza who had given a mailbomb to Chuck (or Frank), who threw it right at Carl's mailcart, blowing it up, prompting Carl to fight back. After the fight, Chuck (or Frank) picked up some Zombrex from his bag, and with his last dying breath, Carl signed his own clipboard, pulled out another mailbomb, and then died from his wounds as it detonates, blowing him to pieces.
