中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

央 = ⺆ + 大 : Mnemonic symbol: 中央处理机, central processing unit (CPU).

In front of the anglepod, Maud Younger received her new robot. Soon she is not satisfied with his artificial intelligence; to increase it, she staples a CPU to the center of its chest, although the robot begs her not to do so.

银 = 艮 + 钅 : Maud Younger spotted a large silver sphere hanging above the entrance to the encampment. She wants to have it and repeatedly throws a golden harpoon at it; to retract the harpoon she uses a chewing gum which she attached to the harpoon, so that it expands to a long rope as she throws the golden harpoon at the silver sphere.

行 = 亍 + 彳 : Mnemonic symbol from "to travel": seven-league boots.

Xi Shi (xi) is tired of walking with a black sneaker on her left foot (彳) and a full armor boot on her right foot (亍). Fortunately she finds seven-league boots (行) in the engine's kitchen ((e)ng2).
