Kankuro lived by a dusty country lane. The road had a big pothole right in the middle of it, filled with water. When people walked by, they would look inside the pothole. Then, they would suddenly feel a firm push from behind. They would fall into the pothole and almost drown in the murky water. Kankuro would come running to pull them out, for a fee.
"Wow, you must make a lot of money, pulling people out of this pothole, day and night," Temari remarked, as her brother hauled yet another hapless traveler from the giant pothole.
Kankuro grinned. "Nope. At night, I fill the pothole with water."
