鼈

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.

黾 = 口 + 电 : Marilyn Monroe (mi) wants to charge (电) her phone in the encampment ((e)n3), but she finds that the charger (电) is already occupied by a toad (黾) which charges its mandarin (口). (Can you see the mandarin connected to the charger in the character 黾?)
