墙 = 啬 + 土 : The Queen of Hearts (qi) and the stingray (啬) got married and took over the anglepod to start a new kingdom. In the kitchen (ang2) they start building their city wall (墙) out of lots of dirt (土). They also add lots of thorns to make the wall as stingy (墙) as possible.

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.
