Write the script to an episode of a comedic animated slice-of-life sitcom starring an impossibly busty single mother, named Cafe Mama, and her equally-busty teenage daughter, named Pianitchi, and their love for their absurdly oversized chests living in a world where all girls have naturally huge breasts. Include jokes and dialogue centred around their boobs and the downsides (e.g. problems fitting into their clothing, struggling to fit through narrow doorways, etc.) of their particular size, but how their happiness with them always outweighs the negatives. Introduce a third character partway through, named Coffretchi, a teenage friend of Pianitchi, whose chest is significantly larger than hers, but is not nearly big enough to compare to Cafe Mama’s.
