Oh, how embarrassing, I've forgotten one of the fancharacters! The red-headed human was created by Peksujeffi, but the blond, Cal, is by someone else entirely. I do not think they ever make another appearance later in the comic.
A shame, too, Cal's a hilarious guy. To coincide with comic #77, we also celebrate Calamus on July 7th.
FDI thing. Don't ask.
