|"I was bitten by a snake."
Since ancient times, chickens have inhabited the Mountains of Impossible Height. The first monks built the walls of the Monastery of Spinjitzu extra tall to keep them out. However, they failed and many monks were lost. In order to survive, the monks became faster, stronger, and more cunning, evolving into ninja.
After catching the ninja in their "hot tub," which they made out of a sacred bell, Master Wu gives them a lecture on monks who became ninja and combat strange animals while the chicken was in a nearby box. Wu then tells them to survive five minutes with what was inside and left. When the box opened, revealing the chicken, the ninja assumed it was a joke until it suddenly glows with a creepy blue color and attacks them. They all manage to grab the chicken and put it back in the box in less than five minutes.
