不問

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.

问 = 口 + 门 : Willy Walrus sees a mouthwatering mandarin hanging over a door in the floor of the encampment's bathroom. He asks himself: "is it a trap?"
