This poop appears to have something embedded in it that I really hope is not corn, and some sort of white fly flying around it.
What's up with this poop?
The white fly is an eternal fly, and will hurt you if it touches you. Additionally, if the poop is destroyed, the eternal fly will be reincarnated as a tougher red fly.
You must choose for yourself whether or not to disturb the eternal fly's slumber - as far as I can tell, its drops are identical to normal poops.
