碧玉

碧 = 珀 + 石 : Brunhilde (bi) is using the space station's bathroom (Ø4), but today she is feeling very unwell. All she produces consists of rock (石), amber (珀) and green jade (碧).

玉 = 丶 + 王 : Mnemonic symbol: a jade bracelet.

Yu the Great (yu) and Martin Luther King (王) invented some kind of wrestling sport in the space station's bathroom (Ø4). Both fighters have to be restrained by large jade bracelets (玉) around their body restricting their arms to be aligned to the body. Then they fight. To make things safe they stuffed the space station's bathroom (Ø4) with cosy petals (丶) so that they won't hurt themselves.
