You see a triceratops in the distance. But, it's odd. It's perfectly pi shaped (that is, circular). Some kind of piceratops, if you will. The reason they are this shape is because they want to absorb as much sunlight (or just light is fine, too) as possible. They evolved to be round so they don't have any corners casting a shadow.
As you watch this majestic beast absorbing sunlight, suddenly several dozen feral (こういち)s burst from various hiding spots, spears in hand. Oh no! Those こういちs are hunting this rare piceratops!
