面壁思過

面 = 丆 + 囬 : Mnemonic symbol: a spray flask with one of these liquids which make a surface super slippery.

In the anthill's bathroom (an4), Marilyn Monroe (mi) wants to set up a wind wheel (丆) on top of a closet (囬). Just as she tries to fix it she slips and falls down, the wind wheel crashing on the floor. She didn't notice that somebody used a can of non-stick coating (面) on the closet's surfaces (面).

壁 = 土 + 辟 : Brunhilde (bi) was checking out the safety of the space station and found that the bathroom (Ø4) is a weak spot in the defence line if there should be any attacker. Thus, she decided to build a rampart (壁). She cannot do it alone though, so she asked the jade dragon (辟) for help. Together, they build the rampart out of earth (土). In this way, they will be able to fend off (辟) any intruder.

思 = 心 + 田 : Socrates is feeling blue in front of the space station. He's thinking of burying his heart under a field. When he finishes, he realizes that he has created some kind of small planet, with his heart at the center.

过 = 寸 + 辶 : Gitta Giraffe is trying out her new gladiator sandals in the observatory's bathroom. She's even able to cross a puddle of water with them by just walking on the water, so thumbs up for her!
