Ep 11. Little Dipper

In Gravity Falls season 1 episode 11, titled "Little Dipper," the twins Dipper and Mabel Pines enter into a rivalry to determine who is the taller sibling. Mabel, who is one inch taller than Dipper, constantly gloats and teases him about her taller height. The competition begins to escalate, with Dipper trying various methods to appear taller, from using height-enhancing sneakers to stretching himself on a rack.

Meanwhile, their great-uncle Stan hires a scientist named Marius von Fundshauser to work at the Mystery Shack. Marius is an eccentric inventor who has created a shrinking device called the "Sapacitator," which has the ability to shrink objects to a miniaturized size. Excited by the potential of the device, Dipper convinces Mabel to help him use the Sapacitator to shrink themselves down to see if they will appear taller at a smaller size.

The plan goes awry when Marius accidentally switches the settings on the Sapacitator, causing Dipper to shrink to the size of a tiny doll while Mabel remains at her normal size. Mabel, now worried about her brother, must navigate the dangerous world of the Mystery Shack, avoiding curious tourists and the family's pet pig, Waddles, while searching for a way to bring Dipper back to his normal size.

As Mabel continues her search, Dipper finds himself in the middle of a miniature battle between Marius' tiny robots and a group of miniature gnomes who are trying to steal the Sapacitator for their own nefarious purposes. Dipper ends up teaming up with the gnomes, who promise to help him return to his normal size if he helps them defeat Marius' robots.

Back in the real world, things get even more complicated when Stan discovers that his new employee is not who he seems, and a secret past comes to light. With the help of Soos and Wendy, the trio plots to stop Marius from using his invention for evil purposes.

Will Mabel find a way to bring her shrunken brother back to his normal size before it's too late? Will Dipper be able to help the gnomes defeat Marius and get back to his normal life? Tune in to "Little Dipper" to find out.
