Write the script for an episode of a comedic animated slice-of-life sitcom starring a babyish, infantile-acting single mother, named Cafe Mama, and her much-more-grown-up, sweet but easily embarrassed teenage daughter, named Pianitchi, and their love for diapers living in a world where the usage of absurdly oversized diapers is universal and are ubiquitously worn by everyone, toddler, youngster, teenager and adult alike. Include jokes and dialogue centred around their huge diapers and the downsides that come with wearing them (e.g. problems walking/waddling with them on, problems fitting their clothes over them, struggling to squeeze through narrow doorways, etc.) but how they wouldn't have it any other way, even if they need frequent changes because of their frequent accidents.
Introduce a third character partway through, named Coffretchi, a close teenage friend of Pianitchi and a skilled designer at a diaper store.
