Mnemonic symbol from 辟邪, to ward of evil: a jade dragon, because this is what you get if you google image search 辟邪. Pocahontas (pi) stored some delicious kimchi (辛) in the space station's bathroom (Ø4), and a ghost (尸) is trying to eat it all in one gulp. Pocahontas is prepared though and uses a jade dragon (辟) to fend off (辟) the ghost. She does throw a mandarin (口) to the desperate ghost though.
