Black Market

You walk up to a wiry rat with a crazy look in his eye. 

"You wanna give it a try? Throw this ball at that target and try to dunk the mouse up there!"

The rat hands you a ball. You see a red and white circular target right next to a mouse on a seat above a large tank of greenish, murky water. The mouse is trembling.

"Please! Please don't do it!"

"Ah, Tucker up there just likes to mess with ya! He actually loves being dunked."

"You'll kill me! Don't throw the ball! Please"

"Oh, Tucker, you silly little guy."
