單個兒

单 = 丷 + 田 + 十 : In front of the anthill there are many, really a field of crosses because Don Quixote killed so many people on his crusades. Today is his judgement day: a mean crocodile reads the list of his victims to him, and Don Quixote is really 不好意思.

个 = 丨 + 人 : Mnemonic symbol: Neanderthal Man (人). Neanderthal Man (人) needs to use the elevator's bathroom (e4) but it's occupied by Guy Fawkes (g), and there's only space for one individual (个). Impatiently Neanderthal Man knocks on the door using his dinosaur bone (丨).

儿 = 丿 + 乚 : Mnemonic symbol: "son" (儿) sounds similar to "Sun" like in "Sun Wu Kong", so it's gonna be represented by the monkey king. Albert Einstein (Ø-) and Sun Wu Kong (儿) are fighting in the space station's kitchen (-Ø2). Their weapons: Albert Einstein has a shovel (乚), and Sun Wu Kong has a banana (丿).
