青少年

青 = 龶 + 月 : Mnemonic symbol: a cyan-colored fountain of youth.

青 = 龶 + 月 : The moon opened a very profitable start-up in front of the engine. He put up a fountain of youth and--wearing a fancy headdress--charges the Queen of Hearts a fortune for drinking from the fountain.

少 = 丿 + 小 : Mnemonic symbol: 少 looks like a smiley face.

There's a food shortage (少) in the aorta, and Sherlock Holmes (sh) and Smiley (少) are looking for food in the living room (ao3). There's only one banana (丿) left. Soon they'll have to eat the many daisies (小) which are growing there.

年 = 午 + 丨 + 一 : Nefertiti (ni) is having lunch (午) in the anthill's kitchen (an2). Unfortunately they didn't have any cutlery left so she has to use a dinosaur bone (丨) and a flute (一) instead of fork and knife. It will take her a whole year (年) to finish her lunch this way.
