Tumbleweeds

• Once either loop is completed, rather than continue to repeat their 'finished' state, there's a new award: Tumbleweeds.

• Each 'full loop' shot counts as a tumbleweed, and each one is slightly more valuable than the last.

• After a set number of completed tumbleweeds, Cowboys VS Aliens is enabled, and will start the next time the game can trap the ball.

• There's a high score category for the most tumbleweeds in a single game.
