貧乏 vs 金持ち vs 超金持ちバービー! 誰が一番強いのか？

Three Barbie girls—BB (poor), Suzy (rich), and Hannah (ultra-rich)—arrive at school in their own distinct ways and sign up for a dollhouse decoration contest. Through three rounds of challenges covering the exterior, bedroom, and ground floor, each girl unleashes her creativity in her own unique style: BB goes for simple and crafty, Suzy brings a soft and trendy vibe, while Hannah opts for lavish luxury. Throughout the process, instead of fierce rivalry, they occasionally offer a helping hand to one another. In the end, all three design stunningly impressive dollhouses. However, thanks to her exceptional creativity using simple materials, BB claims first place, while Suzy and Hannah happily congratulate her on the well-deserved win.
