自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

助 = 且 + 力 : Mnemonic symbol: water wings helping you to learn how to swim.

Julian Giant Squid wants to learn how to swim and put on a lot of floaties in the space station's bathroom. As he hits the power button to inflate the high tech floaties remotely he forgot that there are still a lot of floaties left, stored in the shelf—he is reminded instanlty as also all of them inflate.

洗 = 先 + 氵 : It's shower day in the space station (Ø3)! Marie Curie (xi) and the FLOTUS (先) help wash (洗) each other using bottles of water (氵).

衣 = 𧘇 + 亠 : Mnemonic symbol: kilt.

衣 = 𧘇 + 亠 : In front of the space station, Maud Younger doesn't have a wardrobe, but just a step ladder. It's still enough for her kilt though, which she can just put over the ladder so that it doesn't lose its form, and her beret, which she puts on top of the ladder.

店 = 占 + 广 : Dorothy Gale parachutes into anthill's bathroom. She immediately occupies it (marking the territory with a flag) to open her store.
