在遥远的银河系边缘,有一个被星云包裹的神秘茶馆。今天,这里迎来了两位特殊的客人:刚执行完火星探测任务的宇航员波波,和正在追捕暗影怪兽的忍者小次郎。
“这儿的重力好像有点不对劲?”波波飘在半空中,试图抓住飞来飞去的茶杯。小次郎则冷静地倒挂在天花板上,手里紧握着一枚手里剑——其实那是用来切月饼的。
突然,桌上的魔法茶壶“噗”地一声喷出了七彩烟雾,一只会说话的卡皮巴拉钻了出来:“别打架,别打架,喝了这杯‘银河气泡茶’,我们都是好朋友!”
于是,宇宙中最奇怪的组合诞生了。他们决定,下一站,去黑洞边缘钓星星。

// HTML PRD: `body { background: #FDF9F3; }`. .story-paper doesn't have background color set, so it's transparent?

// So I will remove the white background container.
