大相径庭

大 = 一 + 人 : The big (大), huge (大) robot (mnemonic symbol for 大) is working out in the ashram's bathroom (a4). He's lifting a flute (一) to which Don Quixote (d) and Neanderthal man (人) are clinging.

相 = 木 + 目 : Mnemonic symbol: I take "eye" and "tree" as resembling an ent, an alive tree. Xi Shi (xi) portrays (相) an ent (相) in the anglepod's bathroom (ang4). Unfortunately she's really bad at painting, and her portrait resembles more a Christmas tree (木). The Eye of Providence (目) enters and, just from the shape of the Christmas Tree, instantly recognizes its own portrait (相).

径 = 圣 + 彳 : Father Christmas (圣) gives black sneakers (彳) to Joan of Arc (ji) in the engine's bathroom ((e)ng4). Joan of Arc happily puts her new shoes on instantaneously and circles father Christmas on a track (径) with a very small diameter (径), making father Christmas feel quite uncomfortable.

庭 = 广 + 廷 : Mother Teresa (ti) wants to one-up her palace courtyard (廷) for the cat-o-nine tails in the engine's kitchen ((e)ng2). She upgrades it to the main hall (庭) by covering the walled courtyard with a parachute (广) as canopy.
