In the town of Gravity Falls, OR, anything can happen and usually does. As the heroes of Disney’s Gravity Falls, twins Dipper and Mabel Pines (voiced by Jason Ritter and Kristen Schaal) have to contend with school-age rivals, mind demons, and, perhaps worst of all, gnomes. (Shudder!) On the episode that will air tonight, Monday August 11th, at 9:30pm on Disney XD, the twins will have to contend with the weirdest thing yet – tiny critters who run the mini-golf course.

In this exclusive clip, we see them meet Franz, the leader of the Lilliputtians (voiced by Patton Oswalt), who control all the balls in the course. If you ever wondered what happens to your brightly-colored ball as it goes into the dragons mouth, the mummy’s tomb, or through the windmill, this episode finally has the answer: it goes through a series of very complex and carefully-regulated twists and turns manipulated by a race of small brightly-colored people with Prince Valiant haircuts. Yeah, guys, that really happens.

Things begin to get a little out of control when Mabel challenges her arch rival, Pacifica Northwest (Jackie Buscarino), the most popular girl in Gravity Falls, to a miniature golf contest, with the Lilliputtians acting as her personal caddies. The whole thing can easily be explained in the name of the episode: “The Golf War.” Get out your putting wedge and throw away all other clubs because this is about to get small (meaning both petty and the size of the Lilliputtians).

Gravity Falls Season Two is airing now, on Mondays at 9:30pm ET, on Disney XD.
