土耳其玉

土 = 十 + 一 : Tommy Turtle (tu) wants to fix a cross (十) on a flute (一) in the space station's living room (Ø3). He uses dust and clay (土) to hold them together.

It ist what it looks like: an ear.

其 = 目 + 八 : Looks like a watchtower. The Queen of Hearts is on lookout on the watchtower just inside the space station's entrance. The Eye of Providence helps her to look out for intruders. They also spread some eight balls for possible intruders to trip on.

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.
