二十多

二 = 一 : Mnemonic symbol: a capacitor, because the two strokes remind me of the symbol in electrical drawings. Albert Einstein (Ø) is experimenting with a capacitor (二) in the space station's bathroom (Ø4). He finds that it's uncomfortable to discharge a capacitor using two flutes (一).

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).

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.
