寸步難行

寸 = 一 + 亅 + 丶 : Kitty Cat is playing with a petal leaf in the encampment's bathroom. She's keeping it in the air by hitting it with a flute and a crowbar. It's so much fun that she thinks to herself "thumbs up".

步 = 止 + 丨 + 丶 + 丿 : Mnemonic symbol: a five-paced viper, 五步蛇.

Bruno Bear (bu) was strolling (步) around the space station's bathroom (Ø4) with a dinosaur bone (丨) as walking (步) stick in his hands. He disregarded the barrier (止) marking the wild, forbidden area lightheartedly and just jumped over it whistling a joyful tune. But shortly afterwards he made a terrible realization: only five paces (步)away there was a five-paced viper (步) hiding under a petal leaf (丶)! Bruno knew the viper was after him, so he tried to keep it at distance using his dinosaur bone and feeding it bananas (丿) while at the same time slowly backing up to the barrier.

难 = 又 + 隹 : Mnemonic symbol: a video game which is almost impossible to beat.

难 = 又 + 隹 : Just inside the anthill's kitchen, Napoleon and a sparrow are trying to beat an insanely difficult video game. After playing and failing all day long Napoleon finally loses his temper and crashes the game wearing two boxing gloves.

行 = 亍 + 彳 : Mnemonic symbol from "to travel": seven-league boots.

Xi Shi (xi) is tired of walking with a black sneaker on her left foot (彳) and a full armor boot on her right foot (亍). Fortunately she finds seven-league boots (行) in the engine's kitchen ((e)ng2).
