Very kind-hearted, if not a particularly bright fellow. Lacks in common sense, and has a terrible attention span. Due to not being able to hold a job, Berguv took pity on him and sort of "adopted" him and Barnaby lives at his house and the daily routine that brings him comfort is checking all the clocks in the household (Berguv collects kitschy cuckoo clocks) and dusting off countertops.

It's difficult to determine Barnaby's age in his human form and he's not a particularly skilled shapeshifter. He's also routinely duped and manipulated by Bob, but he doesn't appear to notice or mind.
