Thread
There’s a small pile of poop (see the radicals small and poop in there?). You have to go through it and break it apart to look for some thread your dog/cat ate. Imagine yourself breaking it apart, looking for this thread. It smells bad, and it’s making you gag. Use this feeling of disgust to help you remember this radical… to help you to remember you’re looking for some thread in the poop to make sure it passed (and you don’t have to do any surgery on your pet!).
