Bud and Missy's mother
From the Super Mario Wiki
Bud and Missy's mother (also can be known as Norman's Wife), is the mother, as the name implies, of Bud and Missy. She is the only member of Norman's family that does not have a given name. She appears in one episode in the TV show, "Mush-Rumors", of The Adventures of Super Mario Bros. 3.
Bud and Missy's mother usually calms the children down when they are in exciting situations, including the part where the children excitedly ask if they are at Wild Waldo's One-of-a-Kind Amusement Park. When Norman's family accidentally drives into a Warp Zone that leads them into the Mushroom Kingdom, she tells the kids that they shouldn't be frightened and she thinks that Norman knows exactly where he is going and that he is going to a gas station to ask directions. After crashing into two walls and setting off a commotion about a wild rumor about aliens, the family's car gets nearly totaled.
The Doomship soon attacks the "alien invaders" only to have Mario and Luigi save the family. The Doomship then brings the station wagon via magnet to Kastle Koopa. Bud and Missy's mother gets frightened and she says to King Koopa, "Are you Wild Waldo? Because if you are, this is no way to run an amusement park." Before the family can object, Kooky Von Koopa takes the family to his lab to use his new Transmutational Brainwave Analyzer.
After Kooky gets his results, Mario and Luigi break in and save the family from King Koopa's plan. Mario and Luigi then direct the family back into the car, which Bud and Missy's mother thanks, and Norman drives the family back into the Real World where they came from.
