眼皮子底下

眼 = 目 + 艮 : Inside of the anthill, Maud Younger played a prank on the Eye of Providence. She told it that she would apply a mask to alleviate the wrinkles around its eyes, but instead she just covered its whole eye with chewing gum.

皮 = ㇖ + 丿 + 丨 + 又 : Mnemonic symbol: a cow's hide.

皮 = ㇖ + 丿 + 丨 + 又 : Just inside the entrance of the space station Pocahontas destroys her cow's hide with a sickle because she decided to go vegan. Instead of leather she'll wear a banana peel as coat, boxing gloves as shoes and a big dinosaur bone as long hat.

皮 = ㇖ + 丿 + 丨 + 又 : New mnemonic symbol, since I also use the cow's hide for 革: leather shoes.

子 = 了 + 一 : Zorro wants to eat an egg in the space station, and he already put it in a prize cup, as he has no egg cup. He also lacks a spoon, so he uses a big flute to crush the egg open.

底 = 广 + 氐 : The space station's old concrete foundation has been broken up, and Dorothy Gale wants to send the remnants of the foundation back to the base on earth using parachutes.

下 = 一 + 卜 : Mnemonic symbol: from the up/down logic, and a little bit the shape of the character, a ladder.

Xi Shi (xi) is on a retreat in the ashram. Using a voodoo staff (卜), she divined that next (下) week she'll have to play the flute (一) sixteen hours per day. Because she hates playing the flute, she climbs over the ashram's bathroom (a4) wall using a ladder (下) to escape.
