共軛根式

共 = 井 + 八 : A giant eight-ball is blocking the well in the engine's bathroom. Joining forces together with the communist, Gitta Giraffe and he are able to push the eight-ball off and make the well available to the public again.

共 = 井 + 八 : Mnemonic symbol: the communist.

根 = 木 + 艮 : Guy Fawkes hates Christmas, so he his especially annoyed when he sees a Christmas tree even in front of the encampment. He takes out his chewing gum, sticks it to the tree's star and pulls it as long as he can to see if he can beat his record. Afterwards he wants to wrap the Christmas tree with the chewing gum.

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
