Yaganoopu is a type of soup with Pikachu feces sprinkled with caterpillar piss; the only living creatures that are able to eat this soup without developing acute violent emesis are Sour Patch Kids.
"Do not touch the yaganoopu soup. You will develop testicles on your forehead that will protrude in a very disgusting way."
