十國春秋

十 = 一 + 丨 : Mnemonic symbol: a holy cross. Sherlock Holmes (sh-) is investigating a very strange thing he found in the kitchen of the space station (-2): A big pyramid made of ten (十) crosses (十), which are in turn made out of flutes (一) and dinosaur bones (丨).

国 = 囗 + 玉 : Mnemonic symbol: a nation's flag. Let's say the Chinese flag.

In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.

春 = 𡗗 + 日 : In front of the encampment ((e)n1) Chantal Chicken (chu) and the sun (日) are eating spring rolls (春). The spring rolls are so fantastic that Chantal Chicken and the sun fold their hands (𡗗) and thank their creator for inventing so fantastic spring rolls.

秋 = 火 + 禾 : Mnemonic symbol: from 秋千 (qiu1 qian1), swing (seat hung from a frame or branch).

The Queen of Hearts (qi) celebrates autumn (秋) by offering sacrifices. She puts a bowl of cereals (禾) onto a swing (秋) and has the cereals swing into a fire (火) in front of the outhouse (ou1).
