山谷

山 = 丨 + 凵 : Mnemonic symbol: 山 looks like the tip of a fork. Sherlock Holmes (sh) is climbing a mountain (山) in front of the anthill (an1). He uses a dinosaur bone (〡) as walking stick, and to have better grip he attached a fork (山) to its tip. Unfortunately he accidentally sticks the fork into a receptacle (凵) on the ground of the mountain and gets shocked.

谷 = 人 + 八 + 口 : Mnemonic symbol: popcorn.

Gitta Giraffe (gu) conducts an experiment in the space station's living room (Ø3). She shows Neanderthal Man (人) three things: a mandarin (口), popcorn (谷), and an eight-ball (八), and records how much he likes to eat each of these. Neanderthal Man thinks that the eight-ball is a little crunchy.
