殊不知

殊 = 朱 + 歹 : The wicked witch (歹) sentenced Sheldon Shrimp (shu) to be beheaded (殊) in front of the space station (Ø1), but a vermilion flycatcher (朱) is going to help him. Since the witch is very short-sighted, the bird sits on Sheldon's shoulders acting as his head, flying down as the blade falls down while Sheldon's head is actually behind the guillotine. To the witch it looked like Sheldon's head fell down.

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).
