蟪蛄不知春秋

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

知 = 口 + 矢 : Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).

春 = 𡗗 + 日 : In front of the encampment ((e)n1) Chantal Chicken (chu) and the sun (日) are eating spring rolls (春). The spring rolls are so fantastic that Chantal Chicken and the sun fold their hands (𡗗) and thank their creator for inventing so fantastic spring rolls.

秋 = 火 + 禾 : The Queen of Hearts (qi) celebrates autumn (秋) by offering sacrifices. She puts a bowl of cereals (禾) onto a swing (秋) and has the cereals swing into a fire (火) in front of the outhouse (ou1).
