Psudonym
From Jenny Everywhere Wiki
In one universe, Psudonym was the laid-back human companion of Question Duck, a duck who had a tendency to ask strange questions at random times. Psu once visited a flea market with Question Duck to buy the waterfowl a scarf at a stall that was also being browsed by Jenny Everywhere. Question Duck then asked how many walls an oval room could be said to have. (COMIC: Question Duck 059)
Behind the scenes
Question Duck's human companion was one of the main characters of the Question Duck webcomic. Though they were never, to the Wiki's knowledge, named in-story (certainly not in the Jenny Everywhere crossover strip), author Psudonym has made comments clearly suggesting the human should be read as a human counterpart of themself.
