中庭

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.

庭 = 广 + 廷 : Mother Teresa (ti) wants to one-up her palace courtyard (廷) for the cat-o-nine tails in the engine's kitchen ((e)ng2). She upgrades it to the main hall (庭) by covering the walled courtyard with a parachute (广) as canopy.
