移动式

移 = 多 + 禾 : Maud Younger (y) and Manny (多) just received their food ration in the space station's entrance (Ø2). It's a bowl of cereals (禾). Again. Both Maud and Manny hate been eating cereals over and over again, so they move and shift (移) the cereals between each other because neither wants to eat it.

动 = 云 + 力 : Doggy Dog notices a lot of smoke when he enters engine's bathroom. Instead of thinking long, he acts quickly and moves to push the fire alarm button.

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.
