曠工

旷 = 广 + 日 : The sun (日) is lecturing Karl Koala (ku) in the anglepod's bathroom (ang4), but Karl Koala rather skips class (旷) by hiding under a wide (旷) parachute (广) and playing video games in his hideout.

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.
