信孚中外

信 = 亻 + 言 : Marie Curie and Rosa Luxemburg are reading a letter of Karl Marx to the public in the encampment's bathroom. To make the message really come across to the people they use a megaphone.

孚 = 子 + 爫 : Mnemonic symbol: a wedding ring.

Frieda Fuchs (fu) wants to marry just inside the space station's entrance (Ø2). As a sign of her trust (孚) she puts a wedding ring (孚) around her eggs (子) and shaves (爫) them.

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

外 = 夕 + 卜 : There's a hole in the wall of the airplane's bathroom (ai4), and from outside (外), a bat (夕) wants to enter. Willy Walrus (w) is very afraid of bats, so he does his best to hinder the bat from entering with a voodoo staff (卜).
