Dipper Pines

Mason "Dipper" Pines (born August 31, 1999, 5 minutes after Mabel Pines ) is a smart, curious, and adventurous 13-year-old boy spending the summer with his Great Uncle Stan in Gravity Falls, Oregon, where he and his sister constantly encounter the town's paranormal side. Armed with a mysterious journal, he is one of the two main protagonists of Gravity Falls, who dares to investigate the mysteries of his summer home throughout the summer.

Early life
Dipper was born on August 31, 1999, five minutes after Mabel. His family lives in Piedmont, California. From a young age, Dipper's mother would dress him up in a lamb costume and have him perform his signature song and dance, the "Lamby Lamby Dance." He and Mabel were raised unreligiously, but celebrate all holidays at her insistence. Since he was young, his favorite holiday has been Halloween, of which his favorite part is trick-or-treating with Mabel. He is also known to have been teased about his birthmark by other children until he started hiding it, which may be how he earned his nickname when he was no older than five. He attended Eggbert Elementary with his sister.

Arrival in Gravity Falls
Sometime during the month of June, Dipper and his twin sister Mabel were sent from Piedmont, California to the small town of Gravity Falls, Oregon, to stay with their Great Uncle "Grunkle" Stan, who runs a tourist trap named the Mystery Shack which doubles as his house. While Mabel adjusts with ease, Dipper initially finds it difficult to get used to his new surroundings.

One fateful day, Stan tasks Dipper to put up hanging signs advertising the Mystery Shack in the "spooky part" of the Gravity Falls Forest, where he discovers a journal written by an unknown and enigmatic author detailing the town's secrets and dangers. Dipper discloses his findings with Mabel and consecutively meets her new boyfriend, Norman, who he begins to suspect is a zombie based on the information in Journal 3. Despite failing to find any incriminating evidence, Dipper confronts his sister on the theory, resulting in an argument. During Mabel's date, however, he notices Norman's right hand falling off on camera, which Norman suspiciously attaches back on, making him fearful that Mabel could unknowingly be in danger.

Using the Mystery Cart with the keys he obtains from the Mystery Shack's clerk, Wendy, Dipper quickly heads to rescue Mabel, and, upon finding her, he realizes that Norman is actually made up of five gnomes stacked on top of each other which are residing in the forest, who planned to kidnap Mabel and force her to become their '' queen." He manages to subdue the creatures and escape with his sister, but they are pursued by a large monster made of hundreds of gnomes. The two end up crashing the Mystery Cart upon arriving at the Shack, and are cornered by the monster. The head gnome, Jeff, informs them that they will do "something crazy" unless Mabel becomes their queen, and in response, Mabel agrees, much to Dipper's dismay. Shortly after accepting the gnomes' ring, she uses the Mystery Shack leaf-blower to defeat the gnomes, impressing Dipper in the process. With all the gnomes finally gone, the two make up and enter the Shack, and in an act of newfound appreciation of the twins, Stan allows them each one free gift, with Dipper choosing a new hat to replace his old one, which was taken by a gnome. Before going to bed, he writes two new entries in the journal, one being that a gnome's weakness is a leaf blower, and the other stating that while Journal 3 has told him to refuse trust from anyone in the town, he knows Mabel will always have his back.

Season 1
In the episode "The Legend of the Gobblewonker," Dipper goes fishing with Stan and Mabel as a family bonding day. When they hear that there is a lake monster in the vicinity known as the Gobblewonker, Dipper and Mabel want to find it and get proof of its existence, and avoid having to spend 10 hours on a boat with Stan while they're at it. Dipper wants to be the first to discover the beast so he can win the prize money and appear on TV. They ditch Stan and go with Soos to find it. Dipper brings 17 disposable cameras just in case they lose or break a camera. In the end, the Gobblewonker turns out to just be a mechanical creature driven by Old Man McGucket, who is looking for attention. Because they felt bad about leaving him, Dipper and Mabel spend the rest of their day with Stan to have their family bonding day.

In "Headhunters," Dipper and Mabel help Stan uncover the case of Wax Stan's murder, due to Sheriff Blubs and Deputy Durland being lazy. Dipper, at Wax Stan's funeral, uncovers that Wax Sherlock Holmes and all the other wax figures had murdered Wax Stan. It was mostly Wax Sherlock Holmes, because he axed Wax Stan's head, and left shabby-shoe footprints in the shag carpet, and an axe, which were Mabel and Dipper's first clues. During their investigation, they first went to interrogate Manly Dan, the lumberjack at the downtown biker joint named Skull Fracture. Manly Dan then reported the axe was left handed, narrowing the suspects to leave Toby Determined, who is left-handed and wears shoes with holes in them. He then revealed kissing a cardboard cutout of Shandra Jimenez, the news reporter, at 10:00 PM, the time of the murder. Dipper didn't find out who murdered Wax Stan until his funeral. Dipper then battled the wax figures, successfully killing some, like decapitating Wax Larry King, whose head is still in the vents, which was revealed in the end credits. He also made Wax Genghis Khan jump into the fireplace. Dipper then only had to battle Wax Sherlock Holmes, the true killer. He led him to the Mystery Shack's roof, and he melted when the sun came up.

After viewing a commercial by Soos' recommendation, Dipper had an encounter with the town psychic, Gideon Gleeful. He believed Gideon to be a bigger fraud than Stan. When Mabel began dating Gideon, he noticed the stress Gideon was placing on Mabel and offered to tell Gideon that Mabel was no longer interested in dating him. After telling him this, Gideon got very mad and lured Dipper into a factory to attack him. Dipper discovered that Gideon had an amulet that gave him the power to levitate objects. Gideon could almost control Dipper with it and came close to killing Dipper several times. Mabel had to come and save Dipper from Gideon by breaking his amulet.

Dipper and Mabel pretend to be thirteen so they can go to the haunted convenience store, Dusk 2 Dawn with Wendy and her friends. Wendy and her friends and Mabel and Dipper are playing around in the store when he goes to get more ice. He then sees a headless brain with bloodshot eyeballs staring back at him. He screams and opens the fridge door again. Surprisingly, the figure was gone. Everyone goes back to see what it was about. He distracts them by pointing out the game Dancy Pants Revolution. Eventually, the group stumbles upon a chalk outline of two bodies. Dipper, claiming once again on being a teenager, lays in it, and the outline turns green and the lights go out. One after one, almost all of Wendy's friends disappear. The store then turns upside down, with the ghosts possessing Mabel. Dipper then realizes that the reason the ghosts were upset was because they were all teenagers. He goes up to the ghost and tells him he's not a teenager; he is, in fact, only 12 years old. Dipper then asks if there's anything he can do to help his friends, so he must perform the Lamby Lamby Dance. After doing so, the ghosts let everyone free.

After failing a manliness tester, Dipper feels that he has to prove his manliness. He ventures out into the forest and has an encounter with Manotaurs. Dipper is later sent by the Manotaurs to conquer the Multi-Bear and bring back its head, as a final test of manliness. The Multi-Bear is very ferocious and threatens to kill Dipper if he did not leave his cave. Dipper refuses and he and the bear begin fighting. Dipper ultimately wins and is going to end it. The Multi-Bear has one last request: to die listening to his favorite song, "Disco Girl." Dipper realizes that he and the Multi-Bear had something in common, and decides not to slay him. He later quits the Manotaurs' league. Crestfallen, he returns to his sister and uncle, who reassure him that, because he stood up for what he thought was right, he is his own man. He was able to grow one little piece of chest hair, but Mabel plucks it out and puts it in her scrapbook.

When Stan hosts a party at the Mystery Shack, Dipper helps set up the party and works the ticket booth with Wendy, viewing it as an optimal opportunity to spend time with her. As he tries to enact a complex plan to get Wendy to dance with him, he finds it increasingly difficult as unexpected obstacles (i.e. Wendy sneaking into the party and Robbie showing up). To help him revise and execute the plan, he opts to use a copy machine he had found earlier to make clones of himself, initially just Tyrone, and later Dippers #3 through #10 and Paper Jam Dipper. When Dipper strays from the procedure by talking to Wendy "like a normal person," the clones deem him unfit to dance with her and un
