The Rover Rogue Boys, who only appeared in this one story, would seem to be a "substitute for The Beagle Boys", as discussed in the text article "The Winds (and Fog) of Change" by Joe Torcivia, appearing in Disney Masters (Fantagraphics, 2018 Series) #21 - Walt Disney Mickey Mouse: The Monster of Sawtooth Mountain (October 2022). https://www.comics.org/issue/2443125/#3600025
Like The Beagle Boys, The Rover Rogue Boys are a trio of burglar-masked, dog-face crooks, only of different and individualized physical dimensions.
In Episode I, Paul Murry draws Gyro Gearloose with hair (or a hairpiece) atop his head - and down the back and sides of his head. In Episodes II and III, the inventor is drawn more conventionally with just a "birds-nest" of hair or toupee between his dome and his hat.
