鳖

敝 = 米 + 冂 + 攵 : Mnemonic symbol: a pair of old worn-out shoes.

Brunhilde (bi) has been on a treasure hunt for weeks now because she found an old map (冂). For her hunt she brought a sack of rice (米) which she already more or less used up. After digging up the floor of the space station's bathroom (Ø40) with a sledgehammer (攵) at the point indicated on the map, she finally finds the treasure: a pair of old worn-out shoes (敝) which were incredibly valuable to the owner, but are worthless for Brunhilde.

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.
