Tumbleweed Terror

Tumbleweed Terror is a western themed pinball machine that Soos, Dipper, and Mabel become trapped in, in Soos's story in "Bottomless Pit!". It was made by Ballway Games in Redmond, Washington.

History
Tumbleweed Terror has been in Stan Pines' basement for a long time, and has been played by "SAL," "GAFF," and "POO," who had all gotten the highest scores. In an attempt to beat these three, Soos spent four years playing the game.

The sentient skull inside has a cowboy hat, a handlebar mustache, a gold tooth, and red eyes.

After losing a life, Soos beats the high score by cheating with Dipper and Mabel, by tilting the machine, but the skull in the game realizes it and sucks them into the machine. Disgusted by their dishonesty, the skull attempts to punish them by using features of the game, for example, the “multi ball” setting where a series of pin-balls are spewed from the skull’s mouth.The trio plans to escape by pressing the off button, but Soos states that if it is turned off, all data will be removed, including his high score. After thinking, Soos decides to press it off and they return to normal.
