Nathan and Mozzarella should be pretty obvious at this point, but Colby is what I decided to name the gray mouse from my "cesarean unbirthing" comic instead of just calling him Gray, and Hamand was just a doodle to fill the last quarter and given a name because I was thinking like "Hamand (mouse named after cheese) sandwich" or "Hamand lettuce sandwich" and so on. Hammond would've been a better way to spell the name but I didn't care.
