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 store to prepare for Summerween. The locals wanted to celebrate Halloween twice a year so they made up Summerween. Soos finds cackling skulls in the store and he turns one on. Mabel and Dipper are trashing the store while Grunkle Stan gets stuff for scaring children. The cashier calls security. When Grunkle Stan hears, he throws a smoke bomb 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".

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 to 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. 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, its 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. The Summerween Trickster tells everyone to deliver him 500 pieces of candy by the time all the Jack O' Melons go out or else 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. So, Mabel decides to dress Dipper up and act cute whenever they go to houses. Eventually, they get a ton of candy and they end up with 499 candy pieces. Mabel decides to go get the last piece with everyone but Dipper. Unfortunately, Wendy and Robbie arrive in their van and Dipper takes off his Summerween costume and puts the 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, and 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. Soon, everyone blows the candles of their Jack O' Melon out. Dipper, Mabel, Grenda, and Candy stop Old Man McGucket from setting off 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 and destroys him. 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 and 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 which was seen earlier and the Summerween Trickster finds them. The Summerween Trickster reveals to be a bunch of pieces of "loser candy" no one has ever eaten. 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.

Grunkle Stan finally manages to scare the two kids because they accidentally saw him naked. The kids drop the huge sacks of candy. 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. Everyone watches TV while laughing.

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