刺兒

刺 = 刂 + 朿 : The King of Chu (c) got a thorn (刺) stuck in his chest, and he cannot pull it out because it broke off and the tip is deep under the skin. He has no other choice but to use a kitchen knife (刂) to cut it out in the space station's bathroom (Ø4), but he slips and accidentally stabs himself (朿).

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).
