运送

运 = 云 + 辶 : Yu the Great (yu) is practicing step dancing in the encampment's bathroom ((e)n4). She is wearing gladiator sandals (辶) and is moving (运) so fast that she's evaporating the floor. There are even clouds (云) of smoke coming from her gladiator sandals and the evaporated floor.

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.
