不規則四邊形

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

规 = 夫 + 见 : In front of the Eiffel Tower, each year there are more and more surveillance cameras. A construction worker tries to find his way through this maze, but even his compass is of no use. However he's lucky that Gitta Giraffe is there: she's large enough to just see over the cameras to get an overview and tells the worker the way through the maze.

则 = 刂 + 贝 : Mnemonic symbol: 武则天 (Wu Zetian), the only female emperor of China in more than four millennia. It makes sense because for sure she wrote many official statements, for which 则 is the classifier.

则 = 刂 + 贝 : Just inside the elevator's kitchen, Zorro found a crab. He already has a kitchen knife in his hand and wants to kill and eat the crab, but Wu Zetian quickly writes an official rule that forbids the eating of crabs, much to Zorro's disappointment.

四 = 儿 + 囗 : Mnemonic symbol: a four-leaved clover. Socrates (s) is working out in the bathroom of the space station (Ø4). He's lifting four (四) wooden boxes (囗), and wonders why they are so heavy. He doesn't know that inside one of the four boxes, the monkey king (儿) is hiding and secretly laughing at him - until the monkey king comes out and surprises Socrates with a four-leaved clover (四).

边 = 力 + 辶 : Brunhilde fell down on the sidewalk in front of the anthill. One of her gladiator sandals got stuck in a electricity line at the side of the inn.

形 = 开 + 彡 : Marie Curie (xi) is modding her fake Santa Clause beard (彡) into a new shape (形). With a bottle opener (开) she carves the beard in the engine's kitchen ((e)ng2) so that it gets a fractal (形) shape (形).
