亻 = 丿 + 丨 : Mnemonic symbol: Rosa Luxemburg. She's quite radical, and her name starts with "r", just like "ren2". Also, 亻appears at the left-hand side of characters, and Rosa is a leftist as well.

Robinson Crusoe (r) and Rosa Luxemburg (亻) are having their favorite snacks in the encampment's kitchen: Rosa is eating a banana (丿) and Robinson is eating a dinosaur bone (丨).

盾 = ⺁ + 十 + 目 : Doggy Dog (du) urgently has to visit the bathroom so he storms into the encampment's bathroom ((e)n4) to pee on the banana tree (⺁), but the eye of providence (目) is determined to protect the tree standing guard armed with a cross (十) and protected by a shield (盾). The eye of providence is so determined to stop Doggy Dog because it'll have to clean the bathroom later.
