Most of the New Donkers, both male and female, wear gray business suits. The male New Donkers also wear ties, gray fedoras, and shiny black shoes, while the female New Donkers wear gray sunhats. The only New Donkers who do not wear gray attire are the members of Pauline's band, who all wear red attire and black fedoras with a white band around it, and the Crazy Cap employees. None of the New Donkers are ever seen without their hats, except for at least two members, as they are required to collect Power Moons, where Mario must capture them to control an RC car in order to obtain said Power Moons.
As with other kingdom residents, several New Donkers can be found visiting other kingdoms after finishing the main story. The one who was found in Tostarena can also be found travelling in his taxi throughout the kingdoms with the Desert Wanderer.
Like many of the supporting characters, New Donkers will cower and refuse to talk to Mario if an enemy gets too close to them, regardless of whether Mario has captured the enemy in question or not.
