For her research she earned a graduation cap (宀).

观 = 又 + 见 : In front of the anthill several surveillance cameras are closely observing Gitta Giraffe's boxing training progress. She also closely watches the cameras and practices her punches until she is ready to box every one of them into oblivion.

世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.

界 = 介 + 田 : Joan of Arc wants to leave this world and sets up a rocket launch field in the elevator's bathroom. The field looks like a normal crop field, except that there's a rocket in the middle and that the Joan of Arc marked the boundary with white and red tape.
