Three graphics hacks in one! This hack changes Mario and Luigi into either completely new characters for Custom Plumber 1 and 2, or Captain Lou Albano and Danny Wells (their actors in the Super Mario Bros. Super Show) for Custom Plumber 3! Their palettes and names are modified too, but not the title screen because the editor kept glitching.
