极乐世界

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.

乐 = ⺁ + 朩 : Mnemonic symbol: a cheerleader

乐 = ⺁ + 朩 : In the elevator's bathroom, the cheerleader is beating Lancelot on the head with a banana tree just when Lancelot isn't watching, and laughing at him cheerfully. The cheerleader sneaked up on Lancelot by popping out of a sewage pipe.

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.
