中央企业

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.

企 = 人 + 止 : The Queen of Hearts (qi) and Neanderthal Man (人) plan (企) to open a business (企) inside of the space station (Ø3). Their plan is to produce barriers (止) and send them down to earth.

I can't help but see a bullfrog in 业. Maud Younger finds that the climate in the elevator's bathroom are perfect for her new business: growing bullfrogs.
