雪中送炭

雪 = 彐 + 雨 : Xu Xian (xu) got into very bad weather in the elevator (e3). It has been snowing (雪) a lot, so everything is covered in snow. But now it is raining (雨)! Xu Xian uses a pig snout (彐) above his head to protect himself from the rain while he carefully moves on the slippery ground.

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.

送 = 关 + 辶 : Mnemonic symbol: a delivery girl.

Inside of the engine's bathroom, the delivery girl gave a parcel to Susan Saint Bernard in passing since she can't stop her new electrical gladiator sandals. Susan Saint Bernard recognizes her demise and uses her spider-superpowers to push the off button of her sandals so that she can rest for a while.

炭 = 山 + 灰 : Tecumseh (t) had a fire running in the anthill's bathroom (an4), but now it has already died down. With a fork (山) he is searching in the ash (灰) for the pieces and bits of charcoal (炭) that have formed during the fire.
