Bowsette is the single mother of her only daughter; Bowsette Jr, or June for short. Bowsette is always concerned for her daughter's well being, to a toxic degree. She limits video game time and TV time incrediblely harshly and almost never treats Junior to anything; weather it bs ice cream or a new video game.
She does permit board games though, and loves them.
Bowsette and Junior moved to America because of Bowsette's new job as a production manager.
Junior is not a brat.
