凵

山 = 丨 + 凵 : Mnemonic symbol: 山 looks like the tip of a fork. Sherlock Holmes (sh) is climbing a mountain (山) in front of the anthill (an1). He uses a dinosaur bone (〡) as walking stick, and to have better grip he attached a fork (山) to its tip. Unfortunately he accidentally sticks the fork into a receptacle (凵) on the ground of the mountain and gets shocked.

出 = 屮 + 凵 : Mnemonic symbol: 出 tilted 90 degrees looks like "EE". "EE" is an abbreviation for "emergency exit". In front of the space station (Ø1) Chantal Chicken (chu) plugged her thornbush (屮) into a receptacle (凵), but it short circuited and immediately caught fire. Chantal has no option but to use the emergency exit (出) she came out of to go back into the space station.

凶 = 乂 + 凵 : Mnemonic symbol: a vicious (凶) demon mask. Xu Xian (xu) tried out an electric demon mask (凶) in front of the engine ((e)ng1), but now he can't take it off anymore. He already tried to pull the cable out of the receptacle (凵), but it didn't work. Maybe he has more luck using pliers (乂) to pull at the mask.

画 = 一 + 田 + 凵 : Helga Horse (hu) decided to make the ashram's bathroom (a4) more beautiful, so she paints (画) her favourite field (田) on the wall using a flute (一). She doesn't watch out for the receptacles (凵) though, and gets shocked as her flute gets stuck in one of them.

屯 = 一 + 凵 + 乚 : Mnemonic symbol: a trident (屯).

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).

齿 = 止 + 凵 + 人 : Charlie Chaplin (ch) has an aching tooth (齿), and Neanderthal Man (人) is about to help him take it out using an electrical barrier (止) in the space station (Ø3). They attached the barrier to the tooth and as Neanderthal Man will plug it into the receptacle (凵), the barrier will pull out the tooth.

函 = 丂 + 氺 + 凵 : Hamlet (h) is waterboarded in the anthill's kitchen (an2). He is trapped in a metal box (凵) wearing a breathing mask (丂) while being under a continuous stream provided by an aqueduct (氺). He is allowed to send one last letter (函) home, though.
