Write the script for an episode of a comedic animated slice-of-life sitcom starring an impossibly busty single mother, named Cafe Mama, and her equally-busty, sweet but easily embarrassed 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 clothes, struggling to squeeze through narrow doorways, etc.) of their peculiar size, but how their happiness with them always outweighs the negatives. Introduce a third character partway through, named Coffretchi, a close teenage friend of Pianitchi, whose chest is significantly larger than hers, but is not nearly big enough to compare to Cafe Mama's.
