~ Mabel's last words before she leaves Gravity Falls
Mabel Pines (born on August 31, 1999, five minutes before her twin brother) is the deuteragonist of the animated show Gravity Falls. She is the twin sister of Dipper Pines. Energetic, bouncy, and optimistic, Mabel makes the best of every situation. A lover of arts, crafts, and animals, Mabel is a hyperactive 13-year-old girl and is the brawn to her brother's brains. She is the best friend of Candy Chiu and Grenda Grendinator.
Mabel and her twin brother Dipper were spending their summer vacation locked in their room, watching TV, playing video games and talking on the phone. In order to get them some fresh air and out-door living, their parents decided to send them to live with their paternal great-uncle, or "Grunkle" Stan, owner of a tourist-trap called "The Mystery Shack". The two were sent from Piedmont, California, to the small, sleepy town of Gravity Falls, Oregon. Mabel quickly decided it was her "chance to have an epic summer romance," and made good on this initial promise as Mabel has had a replacement potential boyfriend every few episodes. Mabel's first crush would be “Norman”, who turns out to be both an introduction for her to audition her heart to others and a chance to investigate the supernatural for her twin brother Dipper, as Norman had many odd ticks about him.
Norman had slow reaction time, garbled speech and always wore concealing clothes, so both Dipper and Mabel suspected he is not human, Mabel that he is a vampire, Dipper that he is a zombie. As it turns out, Norman was actually a group of gnomes, posing as a teenage boy. The gnomes become possessive and need to be beaten off, leading Mabel and Dipper to their first mystery and subsequent adventure. Though Mabel was excited by the adventure, she was also left glum by the loss of her potential love-interest. To cheer her up Stan allows them to take one thing from the Mystery Shack for free; Mabel's malaise melts away when she decides on a grappling hook - Though Grunkle Stan had something like a doll more in mind, he stands by it.
Through-out the series Dipper and Mabel continue to find strange and exotic creatures and phenomena that Stan and the other locals long since rationalized and become blind to, from ghosts, to magic, to mad-science experiments.
A consistent antagonist becomes Little Gideon Gleeful, a child-psychic who acts as something of a sham-faith minister, claiming he has the answer to everyone's questions, for a fee. Gideon falls for Mabel and though she can see she will not like him, Mabel humors his requests for a date to try to gently let him down, but Gideon never takes "no" for an answer. Eventually Mabel asked Dipper to help break-up with him for her, at which point Gideon shows his true colors by using his powers on Dipper, believing he is trying to get in the way of his true love. Gideon is de-powered (his mantle apparently is a magical amulet he was using to seem psychic) and Mabel learns to be willing to break the hearts of others rather than string them along. Although Gideon in truth wants the Mystery Shack for his own purposes he remains smitten with Mabel, trying to win her back and take-over the Mystery Shack through-out the series.
Mabel Pines is an energetic girl, with a high positive attitude. She is extrovert while her brother is introvert. As first introduced with "Norman", Mabel's romantic life remains quite central for her. She falls for boys frequently, quite often regardless of their feelings for her. Dipper is very important to Mabel and the two are emotionally inter-woven. Though Mabel often disagrees with her brother over his methods, morally they are very in-sync, and when one of the two deviate from what they know is right the other often acts as the other's extended conscience. Mabel tries to become popular and though she never truly succeeds she does make four major friends: the two local outcasts, Grenda and Candy, Wendy - a teenage employee at the Mystery Shack and a pig she wins at the town fair, Waddles. Her quest to become popular is opposed by local debutante, Pacifica Northwest, whom Mabel tries to reach-out to but instead becomes a rival, though eventually the two do become at least tolerant of each other. In particular Mabel becomes fiercely protective of Waddles, being willing to fight monsters to save him without a second thought. She have a deep obsession with Unicorns, as she tape a traffic cone on a horse's head to look like one, which cause her to be banned from petting zoos. according to herself, her first word was "Unicorn". One of her fears is not being cute, as when she was in Stan's mind, when Bill Cipher turn her cuteness to ugliness.
The characters in the cartoon that Lord Dominator from Wander Over Yonder watches are modeled after Dipper, Mabel, Grunkle Stan, and Soos. The Mystery Ship also has its "S" slightly off just like the Mystery Shack. Jason Ritter, Kristen Schaal, and Alex Hirsch all voice their respective parody counterparts. This is actually the first time Gravity Falls did a crossover with Wander Over Yonder.
