傷

伤 = 亻 + 𠂉 + 力 : Sherlock Holmes hurt himself when he got struck by one of the traps in front of the anglepod. Luckily Rosa Luxemburg passes by: she has the key to unlock the power button of the trap system and turns it off, so that Sherlock can free himself.

亻 = 丿 + 丨 : Mnemonic symbol: Rosa Luxemburg. She's quite radical, and her name starts with "r", just like "ren2". Also, 亻appears at the left-hand side of characters, and Rosa is a leftist as well.

Robinson Crusoe (r) and Rosa Luxemburg (亻) are having their favorite snacks in the encampment's kitchen: Rosa is eating a banana (丿) and Robinson is eating a dinosaur bone (丨).

勿 = 丿 + 勹 : Mnemonic symbol from the shape of the character: bat wings. The 丿 strokes look like the fingers of a single bat wing.

The elephant (勹) wants to eat a banana (丿) in the space station's bathroom (Ø4), but Willy Walrus (w) suddenly flies by (using bat wings (勿)), snatches the banana away and shouts "do not!" (勿)

旦 = 一 + 日 : Mnemonic symbol: A big mug, since many people start the day with a mug of coffee.

Don Quixote (d) meets the sun (日) early in the morning (旦) in the anthill's bathroom (an4). Don Quixote is full of energy and can't wait to start into a new adventure, but since the sun is a morning grouch who only just started drinking her mug of coffee (mnemonic symbol for 旦) she cannot stand it and beats him over the head with a flute (一) to calm him a bit down.

𠂉 = 丿 + 一 : Mnemonic symbol: 𠂉 looks like a key.

Imagine a banana you can't open without putting a key into each of the holes of a flute which is painted on its peel.
