I have to come clean: It wasn't meant to be solved. It's from that brain scientist's lines on Gaspar: "I would have been out there collecting telepathopus brains myself, but my doctor said I have a bad case of 'cowfinger.' I have no idea what that is, but he told me to stand a still as possible and it might heal itself. If only I could get people to stop tipping me over. Maybe I should get a second opinion."
