唾面自乾

唾 = 口 + 垂 : Tommy Turtle (tu) sees many tasty mandarins (口) hang on the weeping willow (垂) in the observatory's bathroom (o4), but they are all hanging too high. Nevertheless, they make his saliva (唾) run in streams. He even tries to spit (唾) at them to make them fall down.

面 = 丆 + 囬 : Mnemonic symbol: a spray flask with one of these liquids which make a surface super slippery.

In the anthill's bathroom (an4), Marilyn Monroe (mi) wants to set up a wind wheel (丆) on top of a closet (囬). Just as she tries to fix it she slips and falls down, the wind wheel crashing on the floor. She didn't notice that somebody used a can of non-stick coating (面) on the closet's surfaces (面).

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).

干 = 一 + 十 : Mnemonic symbol: dried fruit.

Guy Fawkes (g) is drying (干) his clothes in front of the anthill (an1). He hangs them on a large construction made from a cross (十) and a flute (一). Waiting for his clothes to dry, he snacks dried fruit (mnemonic symbol for 干).
