電匯

电 = 乚 + 曰 : Dorothy Gale (di) is looking for a wall plug for her charger (mnemonic symbol for 电) in the anthill's bathroom (an4). She's digging up the whole place with a shovel (乚), but instead of a wall plug she finds a microphone (曰).

汇 = 匚 + 氵 : Helga Horse (hu) brought a collection (汇) of water bottles (氵) and a metal box (匚) to the Eiffel Tower's bathroom (ei4). Each bottle contains water from a different river. Finally the moment she's been waiting for arrives: As she empties each bottle into the metal box, she converges (汇) the water of all these rivers at once.
