電工

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).

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.
