涉世未深

涉 = 步 + 氵 : Sherlock Holmes (sh) suspects the five paced viper (步) to have killed an innocent person, so he is looking for it in the elevator's bathroom (e4). The snakes hides in one of the many water bottles (氵), so Sherlock has to wade (涉) through the bottles and the water in order to find the viper (步).

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.

未 = 一 + 木 : Mnemonic symbol: the artist Ai Weiwei. Shortly after finishing a new installation in the Eiffel Tower's bathroom (ei4), Ai Weiwei (未) is imprisoned by Willy Walrus (w), because—out of all places—Ai Weiwei put his new installation right into Willy Walrus's toilet. Ai Weiwei's installation is a Christmas tree (木) with a tiny, slightly tilted flute (一) on top. Ai Weiwei would really, really like to correct the tilted flute, but so far, Willy Walrus has not yet (未) let him out.

深 = 氵 + 冖 + 八 + 木 : In front of the encampment ((e)n1) an eight ball (八) has been fixed to the top of a Christmas tree (木), and on top of the eight ball a cooking top is balanced carefully so that it doesn't topple over. On the cooking top a lot of water bottles (氵) are standing so that everything is perfectly balanced. As Sherlock Holmes (sh) comes along he finds that this construction is very interesting, and he makes a profound (深) mistake with a deep (深) impact: as he takes down only one of the bottles the whole thing collapses and all the other bottles break as they fall on the ground. Soon, Sherlock Holmes is in deep (深) trouble as the water from the water bottles gets deeper and deeper (深).

深 = 氵 + 罙 : Sherlock Holmes (sh) finds a grease fire in front of the encampment ((e)n1). He wants to put it out, but he knows that you shouldn't directly pour water in a grease fire. Instead, to keep a distance from the fire, he pours bottled water (氵) through the top of the chimney above the kitchen range (罙). Soon, the kitchen range is submerged in deep (深) water.
