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.

城 = 土 + 成 : Again Charlie Chaplin is unable to exit engine. There is a wall of dirt blocking the entrance, and a progress bar showing that it will be removed soon, but the bar seems to be stuck.
