多年來

多 = 夕 : Mnemonic symbol: Immanuel "Many" Kant.

Many (多) and Doggy Dog (du) have great fun chasing a bat (夕) in front of the observatory (o1). After a while there are two bats (多), and it's not so easy to chase them any more. Suddenly there are more and more (多) bats! Now Many and Doggy Dog experience what it is like to be chased for a change.

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.

來 = 从 + 木 : Mnemonic symbol: mailwoman. Sir Lancelot (l) is visiting the mailwoman (來) in the airplane's kitchen (ai2). As a gift, he brought a Christmas tree (木) decorated with rubber chicken (从).

来 = 丷 + 未 : Mnemonic symbol: mailwoman. Lancelot (l) is super happy that his inflatable crocodile (丷) and live size Ai Weiwei (未) puppet finally arrived (来). The mailwoman (来) delivered them straight to the kitchen of the airplane (ai2).
