The first episode of ''WesternAnimation/GravityFalls''.

Twins Dipper and Mabel Pines visit their eccentric uncle for a summer in Gravity Falls, Oregon, where he operates the world's most bizarre museum. In the opener, the twins arrive in Gravity Falls and soon discover something amiss in the remote town.

It seems like an average summer day in a small town called Gravity Falls, Oregon. Cookouts are held, children are playing, everybody is having fun. That is, except for the two kids in a golf cart being chased by a giant monster. "My name is [[AgentMulder Dipper.]] The girl about to puke is my sister [[GenkiGirl Mabel]]."

We then go to a flashback that takes over most of the episode. It turns out that the two are over at Gravity Falls for the summer. Mabel looks at it as a positive experience ("Yay: grass!"), while Dipper is more skeptical, and irritated by [[JerkAss Great-Uncle Stan]]. Stan's house is a tourist trap, and uses it to make money. Stan tries to pick a member of his workforce to put some signs up in the forest. Soos and [[ServileSnarker Wendy]] refuse, so Dipper is chosen. He comes across a fake tree, which controls a passage which leads to a Journal containing the secrets of Gravity Falls, and the monsters that lie underneath the small town, such as Ghosts or Gnomes.

Meanwhile, Mabel is trying to get her big summer romance. She then meets a boy, Norman that has suspicious features, including gray skin and bleeding. Mabel is head over heels, but Dipper is suspicious, especially as he reads the book. He comes to the conclusion that Norman is a ZOMBIE. So, he gets Wendy to toss him the keys to the cart ("Try not to hit any pedestrians"), and Soos gives him a bat (in case he runs into a pinata).

However, Norman outs himself... as a bunch of gnomes. Mabel decides to break off the relationship... only for the gnomes to kidnap her to make her their queen. Dipper is able to arrive as they tie Mabel up, rescues Mabel and the two flee. The gnomes turn into a Super Gnome, bringing this episode full circle. Mabel and Dipper are forced to knock out all of the gnomes as they attack. However, the journal shows no permanent weakness for the Gnomes. They arrive at the Mystery Shack, and Mabel pulls a BatmanGambit: surrendering to the gnomes, and then attacking them with the leaf blower (that Mabel used for kissing practice). As they go in, Stan [[JerkWithAHeartOfGold lets them take a piece of merchandise from the store each for free]]. By the end of the episode Stan enters a secret passage behind the soda machine.
