变速器

变 = 亦 + 又 : In anthill's bathroom the also-ran is sparring with Brunhilde. In her mind she imagines changing into a boxing grizzly bear.

变 = 亦 + 又 : I think 变 does look like a grizzly bear with a beret. 又 is the snout, and the two eyes are the two strokes of 八.

速 = 束 + 辶 : Susan Saint Bernard tries out a new way of moving much faster in the space station's bathroom. She attached a bundle of firewood to each of her legs, and attached gladiator sandals to the ends of the bundles. This way she extends her legs and increases her speed dramatically.

器 = 㗊 + 犬 : The Saint Bernard dog has been practising playing his bagpipe all day in the space station's bathroom. The Queen of Hearts is so annoyed that finally she grabbed a screwdriver as utensil to end this torture.
