中组部

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.

组 = 且 + 纟 : Zapatista Zebra (zu) and the silk worm (纟) are starting a NGO (组) in the space station (Ø3). The NGO's goal is to distribute as many space friendly shelves (且) as possible. The shelves are radially symmetric and can be rotated so that the centrifugal force keeps the things in the shelf.

部 = 咅 + 阝 : Bruno Bear (bu) has been harassed by the Imperator (阝) in the space station's bathroom (Ø4), so Bruno sets up a trap. He creates two fake boobs (乳部) out of poo-poo (咅) and as the Imperator grabs his boobs, the Imperator realizes his mistake and exclaims "bah!" (部).
