胃口

胃 = 月 + 田 : Willy Walrus (w) set up a mooncake (月) field (田) in the Eiffel Tower's bathroom (ei4). This led to him eating way too much cake, and now his stomach (胃) hurts. To relief the pain he uses a hot water bottle (mnemonic symbol for 胃).

Mnemonic symbol: 口 shall be represented by a mandarin. Karl Marx (k-) is enjoying a mandarin in the outhouse's living room (ou3).
