男中音

男 = 力 + 田 : Mnemonic symbol: a mankini.

Napoleon (n) is taking part in the iron-man contest. In the anthill's kitchen (an2) he has to rob through a muddy field (田) as fast as possible while wearing a mankini (男). He has to reach a power button (力) located at the other end of the field and push it as fast as possible to qualify for the next round.

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.

音 = 日 + 立 : Mnemonic symbol: a loudspeaker.

音 = 日 + 立 : Maud Younger and the Sun opened a pop-up store in front of the encampment. They sell vases and advertise them using loudspeakers, playing loud music and dancing to it.
