中油

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.

油 = 氵 + 由 : Maud Younger (y) is creating art in the outhouse's kitchen (ou2). She is painting a picture using oil (油) paint and occasionally using water color stored in a water bottle (氵). She is nipping a cuba libre (由) and from time to time even using her drink as color for her picture.
