[[WMG: Junior from "Bellboy Donald" and [=PJ=] from ''GoofTroop'' are the same character]]
Well, there's at least one fanfic of ''HouseOfMouse'' supporting the theory.

[[WMG: Pete lost his leg in WorldWarI, and became a crook to live after the economic crisis took away his pension]]
Also, he was reactivated as an instructor during 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).
