He also appears in "Another Five More Short Graybles," in which he shows his home to the audience, describing its components and discovers that his subconscious self was writing a treasure map for him.
In "Astral Plane" Finn's Astral self visits his home for a few seconds, in which Mr. Fox's astral self is in a chair doing a Sudoku puzzle, while his physical body is sleeping, talking about Boobafina in his sleep. He offers Finn a drink, either forgiving him for ruining his chances with Boobafina or not remembering him at all, but Finn beyond his control leaves for the next location which Mr. Fox deemed "sorta rude."
Mr. Fox looks like his namesake. He can walk on two legs, but runs on four. He has bags under his eyes, but that could be because he was constantly stressed throughout the episode "Storytelling."

- Mr. Fox is the second character to have a subconscious that can touch the material plane. The first is Jake.
- In "Astral Plane," both Finn and Mr. Fox seem not to remember each other at all. While it is understandable for Finn, as he only met him once, Finn was the one who ruined Mr. Fox's chances to be with Boobafina, in which that same scene showed that he is still heartbroken over her. Or rather, Mr. Fox does remember, and was being hospitable due to all the animals having forgiven Finn at the end of "Storytelling" for better or worse. Regardless, after Finn left, Mr. Fox hoped he would return, likely due to being incredibly lonely, which Finn points out immediately afterwards.
- Mr. Fox is stated to be incredibly lonely, and is even hinted at in "The Comet" to be the loneliest being in Ooo. Despite "Jake The Dad" has shown him to have an entire family or gang of foxes that he associates with. Though it could be implied that he may have alienated himself from the rest of his gang/tribe after his plan utterly failed and humiliated them all.
- In "Ocarina" he is one of the many renters, purchasing board at Finn and Jake's home, despite he is shown to have his own house in "Another Five More Short Graybles," "Astral Plane," and "King's Ransom."
- It is said that his voice is based upon a poor Christopher Walken impression from one of the creators.
- In "Come Along With Me," his skull can be seen in BMO's house on Mount Cragdor in the future, where Beth picks it up and drops it.
