In 'Extinction', the guards dress as animals in costumes that have big heads. On each contestants' turns, one of these animals wanders across a shooting range. The contestant, who is a few meters away, has to use the Tani's cannon to fire balls at them - trying to knock off the animal's head.
There are a few rocks and trees for the guards to hide behind, but they usually spend most of their time taunting the contestants.
If a contestant manages to shoot off the animal's head they win the game; but if the animal gets to safety, on the other side of the shooting range, with its head still in place the contestant loses and gets locked in a cage.
