讨

讨 = 寸 + 讠 : Tecumseh (t) is asking (讨) an advertising column (讠) inside of the aorta (ao3) for a little snack, and indeed, the column ejects some chocolate bars, which causes Tecumseh to thumb up (寸) at it.

寸 = 一 + 亅 + 丶 : Kitty Cat is playing with a petal leaf in the encampment's bathroom. She's keeping it in the air by hitting it with a flute and a crowbar. It's so much fun that she thinks to herself "thumbs up".

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).
