礦山

矿 = 广 + 石 : Karl Koala (ku) got a new job at the coal mine (矿) in the anglepod's bathroom (ang4). The entrance to the tunnel lies quite high, so every time Karl brings out another coal stone (石) he attaches it to a small parachute (广) and lets it fly down to the floor.

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.
