[[WMG: Junior from "Bellboy Donald" and [=PJ=] from ''WesternAnimation/GoofTroop'' are the same character]]
Well, there's at least one fanfic of ''WesternAnimation/HouseOfMouse'' supporting the theory.
* His name would be Pete Junior... which he shortens to PJ as a nickname as a kid. Pretty straightforward and reasonable.

[[WMG: Pete lost his leg in UsefulNotes/WorldWarI, and became a crook to live after the economic crisis took away his pension]]
Also, he was reactivated as an instructor during UsefulNotes/WorldWarII, and was Donald's drill sergeant when a bureaucratic error put him in the US Army for a while (he later returned to the Navy).

[[WMG:Pete is actually a crossbreed of a cat and a hippo.]]
This isn't just a joke about his weight. His [[https://disney.fandom.com/wiki/Pete/Gallery?file=Disney%2527s_Peg-Leg_Pete.png#External_galleries mostly hairless muzzle and four large, square teeth]] are unusual for a cat, but they would be fitting for a cartoon hippo. See [[https://disney.fandom.com/wiki/Hyacinth_Hippo/Gallery?file=Fantasia-disneyscreencaps_com-8358.jpg Hyacinth Hippo]], for example. Being half-hippo would also explain why he's so [[AngryAngryHippos vicious and intimidating]].
