Summerween

"Summerween" is the twelfth episode in Season 1 of Gravity Falls. It debuted on October 5, 2012.

Overview
It’s Gravity Falls’ version of Halloween in Summer with Jack O' Melons and lots of trick-or-treating. Dipper and Mabel are excited to join in on the fun, but when Wendy casually mentions that trick-or-treating is for kids, Dipper’s whole outlook on the evening changes. The night gets even more complicated when a monster that Dipper accidentally insulted makes them fulfill his candy quota by the night’s end or else he will eat them.

Synopsis
Dipper, Mabel, Soos, and Grunkle Stan drive to the Summerween Superstore to prepare for Summerween. The locals wanted to celebrate Halloween twice a year, so they made up Summerween, the Halloween in the middle of Summer. Soos finds cackling skulls in the store and he keeps turning them on. Mabel and Dipper are trashing the store, while Grunkle Stan gets some material for scaring children. The cashier calls security due to the distrubance they're making, so Grunkle Stan throws a smoke bomb at the cashier and runs away with the gang.

Dipper and Mabel are planning out Summerween when Soos tells Dipper and Mabel about the Summerween Trickster. If the children do not enjoy their candy, the Summerween Trickster eats them alive. However, Dipper begins throwing out candy that he deems as trashy "loser candy" that Stan had bought to hand out.

The doorbell rings and Dipper goes to get it. Dipper is shocked to find Wendy and Robbie in the door. When Robbie asks if Dipper is going trick or treating, Wendy tells him that Dipper isn't because trick or treating is for kids. Dipper reluncantly agrees with her. Wendy invites Dipper to Tambry's Summerween party, and Dipper says he will go. However, Mabel has invited Grenda and Candy to go trick or treating. Dipper fakes being sick so he can go to Tambry's party. However, the doorbell rings again, and this time it's the Summerween Trickster. Dipper mistakes him for a normal trick-or-treater, says he is too old for trick-or-treating, and slams the door on him. The Trickster knocks on the door again, but Dipper slams it in his face, getting the Trickster angry. Mabel scolds Dipper and opens the door again. The Summerween Trickster now breaks into the Mystery Shack and tells everyone that if they don't deliver 500 pieces of candy to him by the time all the Jack O' Melons in town go out, he'll eat them.

They head over to Lazy Susan's house to trick-or-treat. Because Dipper refused to get dressed up, they only get one piece of candy each, and he receives none. So, Mabel decides to dress Dipper up and act cute whenever they go to houses, which greatly increases their candy yeild. Eventually they end up with 499 candy pieces, and Mabel decides to go get the last piece with everyone but Dipper while Soos goes and gets his truck so they can deliver the candy. Unfortunately, Wendy and Robbie arrive in their van and Dipper takes off his Summerween costume and puts the supply of candy behind a bush.

When Dipper says he will be there soon, Wendy and Robbie take off in their van and Mabel discovers why he faked being sick earlier. It doesn't get any better, the candy has fallen off a cliff behind the bush and into a river because Dipper had not been paying attention, and everyone has started blowing out the candles in their Jack O' Melons. Dipper, Mabel, Grenda, and Candy manage to stop Old Man McGucket from blowing out his Jack O' Melon, but when they breathe a sigh of relief, the Jack O' Melon goes out. The Summerween Trickster then arrives.

Meanwhile, Grunkle Stan is having a difficult time trying to scare two kids. He even uses Waddles to try and scare them, but the kids claim to have been watching horror movies ever since they were two years old. The kids scare Grunkle Stan with a screamer video, and Stan runs back in the Mystery Shack.

Soon, the Summerween Trickster tries to eat Dipper and Mabel, but out of nowhere, Soos drives his truck straight through the monster, smashing him to pieces. Everyone gets into the truck, but Mabel gives Dipper the cold shoulder for not wanting to trick-or-treat with her.

Unfortunately, the Summerween Trickster comes back to life as his pieces re-assemble, and he pursues the truck. Dipper, Mabel, Grenda, Candy, and Soos hide in the Summerween store, and Mabel reveals she was upset with Dipper because she was worried this will be the last time they'll trick or treat.

They are almost in the clear when Soos turns on a cackling skull that he was playing with earlier and the Summerween Trickster finds them. The Summerween Trickster reveals to be a bunch of pieces of "loser candy" no one wanted and tossed in the dump. It eats Soos and then tries to eat Dipper and Mabel. However, Soos starts eating the monster from the inside out. It is revealed that all the Summerween Trickster wanted was someone to enjoy his candy, and he starts crying tears of candy corn as Soos eats him.

Grunkle Stan finally manages to scare the two kids because they accidentally saw him half-naked, and the kids drop their huge sacks of candy while running away. Dipper, Mabel, Soos, Grenda, and Candy finally get back to the Mystery Shack and Dipper confesses to Wendy that he was trick or treating. However, Wendy says the party was lame because Robbie got sick and went home early. In the end, everyone watches TV while laughing. Grunkle Stan then says that Summerween isn't about candy or scaring, but a night to celebrate pure evil. Then Soos says, "I ate a man alive tonight."

In the credits, Mabel decides to take pictures of Waddles in his boss costume with funny captions, similar to the style of LOLCats, with 9 to 5 by Dolly Parton playing in the background.
