Here we have a type 1 shit. The brown stew is encircled by a moat of dark yellow urine, quite common for a morning shitpiss. There's an even ratio of toilet paper to shit. This is good, because we have clear evidence that the father(s) has wiped, and isn't running around with compromised underwear. It is also peculiar because in Korea, it is more common to dispose of used toilet paper in a bin (pictured left) rather than the toilet bowl itself.
Upon closer examination, a careful observer might realize that the fecal volume of this bowl is quite large. I found this specimen at 8:40AM on the 5th/6th grade floor, so while it is by no means impossible for one child to have fathered this, I am hesitant to rule out other possbilities. Perhaps an adult left this in a rush to get somewhere. Someone with a dirty mind, and even dirtier bowels perhaps, who gets off on having others find their pungent presents.
I would not even rule out the possibility that this is in fact, not one shit, but a fecal amalgam left by two vandals working in concert to harm the plumbing infrastructure of our school. Whether or not they were successful has yet to be determined- the shit remains in a state of unflush as I write this.
