=

者
:
Louis XIV (者) built castle walls (堵) out of dirt (土) in the space station (Ø3), but now since the passage through the space station is blocked (堵), every morning when Doggy Dog (du) commutes to work he gets stuck in a traffic jam (堵) caused by the castle walls.
击
=
凵
+
扌
:
Joan of Arc (ji) locked herself out of the space station again. In front of the space station (Ø1) she tries to break (击) the door open using her electric mortar (击). The mortar has to be a few meters away from the door but the receptacle (凵) for its cord is right next to the door, so Joan of Arc plugs the mortar in using a toy claw (扌).
