Mustachio Man is one of Bowser's disguises. This disguise was used in 'Find Koopa!'. He used this mustache to trick the Mario Bros. into handing over there Koopa from the egg. His mustache kept falling off, but Mario Bros. still belived Bowser's diguise. Bowser told them to close there eyes for 10 seconds, when they came up there would be FREE Pizza. While the two fools closed there eyes and counted, Bowser ran off with the Koopa. Mario and Luigi had to get Koopa back.
