In case you've read any of my "Pains of Nursing" stories, these are what the charaters look like. They originally had all black eyes, but I updated that.

These are perhaps the central characters of the series. Boland is actually based on the character of the same name from Hans Wilhelm's "Tyrone the horrible" series. He's the taller one in the pull-ups. The shorter one his is little brother, whom I created, named Andrew. He's running away from Boland to avoid having his diaper changed. Any advice on how to draw Pull-ups is welcome. And as for their species, I still haven't figured it out. It never said Boland's in the book.
