犬
:
The Saint Bernard dog (犬) is out of blood to bring to severe emergency spots, so Marie Curie (xi) volunteered to donate (献) blood in the anthill's bathroom (an4). To make her feel comfortable, the Saint Bernard dog set up a palm (南) from the south pacific.
Mnemonic symbol: this character looks like a big "i" (like in information), and I'll represent it by an advertising column. Maud Younger (y) gives a speech (讠) standing on top of an advertising column (讠) in the anthill's kitchen (an2).
