红萝卜

红 = 工 + 纟 : Mnemonic symbol: a little red book.

Helga Horse (hu) is reading the little red book (红) in the engine's kitchen ((e)ng2), when she discovers that it is being eaten by a silk worm (纟). She overreacts a little and wants to beat the silk worm with a steel beam (工).

卜 = 丨 + 丶 : Mnemonic symbol from "to divine" and the shape of the character: a voodoo staff.

Bruno Bear (bu-) tries to divine (卜) the future in the space station's living room (Ø3). He places a petal (丶) in the middle of the room as an offering and starts a magic ritual with his voodoo staff (卜). The staff transforms the petal into a dinosaur bone (丨). Bruno divines that the staff was trying to tell him that all things are mortal and must come to an end.
