中共中央

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.

共 = 井 + 八 : A giant eight-ball is blocking the well in the engine's bathroom. Joining forces together with the communist, Gitta Giraffe and he are able to push the eight-ball off and make the well available to the public again.

共 = 井 + 八 : Mnemonic symbol: the communist.

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.
