自給自足

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).

给 = 合 + 纟 : Inside of the Eiffel Tower, a little silk worm is exceptional desperate, because she is unable to produce a silken thread. Fortunately Guy Fawkes has a solution: He gives her a tube of glue as a present, which he decorated with a little ribbon. With the glue, the silk worm is able to produce long sticky threads again.

足 = 龰 + 口 : Mnemonic symbol: a football. Zapatista Zebra (zu) wants to pimp his football (足) in the space station's kitchen (Ø2). He thinks that a few more vitamins wouldn't hurt, so he extracts the vitamins from a mandarin (口) with a syringe (龰) to inject them into his football.
