文責自負

文 = 乂 + 亠 : Mnemonic symbol: a thick book.

Willy Walrus (w) wants to cook in the encampment's kitchen ((e)n2). The recipe book (文) is extremely greasy and Willy doesn't want it to touch anything, nor touch it. That's why he puts it into a beret (亠) so that it doesn't touch the floor, and uses pliers (乂) to turn the pages.

责 = 龶 + 贝 : Zorro and the crab started a party in the elevator's kitchen. They wear funny hats and have lots of booze, but they are responsible drinkers and know when they have had enough.

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).

负 = ⺈ + 贝 : Mnemonic symbol: an opossum (负鼠) who carries her babies on her back.

A few pals practice their cosplay on the space station's bathroom. They want to reenact the town musicians of Bremen, and so Frieda Fuchs stands at the bottom, the crab is on top of Frieda, the crane is on top of the crab, the opossum is on top of the crane, and the opossum carries her babies on her back.
