三文鱼

三 = 一 + 二 : Mnemonic symbol: a Cartesian coordinate system with three (三) axes.

Socrates (s-) is performing in front of the anthill (-an1). He created an electrical flute by attaching a large capacitor (二) to the flute (一), so that he can get the attention of all the ants. Moreover, he's balancing on a Cartesian coordinate system (三). Unfortunately, only three (三) ants stop to watch the performance.

文 = 乂 + 亠 : Mnemonic symbol: a thick book.

Willy Walrus (w) wants to cook in the encampment's kitchen ((e)n2). The recipe book (文) is extremely greasy and Willy doesn't want it to touch anything, nor touch it. That's why he puts it into a beret (亠) so that it doesn't touch the floor, and uses pliers (乂) to turn the pages.

鱼 = ⺈ + 田 + 一 : Yu the Great set up a small rice field just inside the entrance of the space station, and there are some fish swimming in the rice field. The space station's crane spotted them and wants to snap one out of the rice field, but just as he was about to snatch one of them, Yu the Great hit him with a flute.
