A gang of Sewer Children was trying to warn you that this was their turf but since you did not listen they are now punching and kicking your head.
You discover later that this gang lives on stolen peanuts which are the perfect sewer ford. Wrapped up tight each peanut is fresh and clean.
This gang was apparently burned to death by a Social Cleansing Death Squad before you could extract your revenge. You remain in the area you were staying in. It was probably the peanut farmers who raised the death squad on "The Peanuts Gang".
Your poops are free from anyone else's and your mandala pattern is exquisite in detail. A three dimensional accretion of your organized fecal amid the chaotic and meaningless defecation of the above world.
