"Little Gift Shop of Horrors" is the sixth episode of the second season of Gravity Falls and the 26th episode overall. It premiered on October 4, 2014 on Disney Channel. This episode is also the second and final Halloween special of the series.
In three separate mysterious tales, Stan is cursed by a Witch, Waddles accidentally eats a bowl of brain-enhancing goop and builds a machine that allows him to speak for the first time, and Mabel faces her fear of Claymation.
The episode begins with Stan welcoming a person (shown from first-person view) whose car broke down at night into the Mystery Shack, warning the traveler that he may be subject to "Tales Designed to Sell My Merchandise!"
Stan explains that after hours, the Mystery Shack has its spookiest attractions for sale. He offers the person a disembodied hand, which is ridiculously expensive. To support this, he tells a story called "Hands Off."
At breakfast, the twins discover that Stan's hands are missing. A message from the witch plays on the watch, but Stan angrily interrupts it, also refusing to listen to Dipper's suggestion to simply return the watch. When his stumps make breakfast difficult, he asks Mabel to make him new hands, but those work poorly too. Dipper, Mabel and Stan visit the witch's secret hideout in mountain cave, which they locate using a pamphlet from the swap meet. The cave is populated by disembodied hands that promptly attack them. The hand witch reveals herself. Stan returns the watch, but she claims the curse can only be broken by a kiss. Stan relents and kisses the witch's hand, but loses his nerve when the witch claims it was supposed to be a kiss on the lips.
The witch confesses that the hand stealing is a ruse meant to get her a date, but that the plan always ends in failure. Mabel suggests a home makeover to attract potential dates instead, and the Pines, with help from the disembodied hands, remake the cave. The grateful witch returns Stan's hands to him. After Stan and the twins leave, a mountain climber turns up. The witch proceeds to flirt with him using a book Mabel gave her, and is apparently succesful.
After the story, the person says they don't want the hand, so Stan tosses it and the hand crawls away. Stan spots Waddles on the ground and offers to sell him, calling him a magic pig.
Dipper orders a new puzzle toy, the "what-the-heck-ahedron", which promises to feature the person who solves it on its box. He finds it incredibly difficult, and Mabel suggests he might just not be smart enough to solve it. Affronted, Dipper locates the "percepshrooms" which Journal 3 says will increase brainpower when ground up and smeared on the forehead overnight. Dipper does so, but soon after falling asleep, Waddles wakes up and eats the ground mushroom powder off of Dipper's forehead.
The next morning, the twins wake up to see that Waddles has become a genius: he has built a vehicle, with aa device that allows him to talk, and has also solved Dipper's puzzle toy. Dipper eagerly welcomes the new Waddles, but Mabel is heartbroken, as Waddles no longer wants to play with her, preferring to spend his time inventing. Dipper and Waddles work together to create inventions, eventually building the "Smarticle Accelerator," which will let Waddles solve all the mysteries of the universe. Mabel is left on her own.
Mabel asks Waddles to remember all the fun they used to have. Waddles realizes that there is no point in helping the world if he can't help his favorite person in the world. He then activates the Smarticle Accelerator's reverse switch, reverting him to an ordinary pig, and causing the device to collapse. Dipper is devastated, but Mabel says a hug from Waddles will cheer him up. Dipper hugs Waddles, and the pig regurgitates the What-the-Heck-A-Hedron, which Dipper cheers him up more, but finds it a bit gross.
Back in the Shack, the person refuses Waddles as well. Stan replies by offering some spooky VHS movies.
Dipper, Mabel, Stan, and Soos are watching a movie called "Believe in Yourself," which only Mabel likes. Stan puts in "The Voyages of Loinclothiclese." To Mabel's dismay, the film has claymation, which Mabel has a childhood fear of. She goes and hides in a laundry basket until Stan decides to take everyone to the house of the film's director, Harry Claymore, to prove claymation is harmless.
Claymore's house is somewhat old, and Stan, Dipper, Mabel, and Soos soon discover that it is inhabited by a giant clay cyclops and clay skeletons. They find Claymore tied up, and he explains that he used black magic to make the clay figures animate themselves. However, when computer animation was invented, the figures were out of a job, so they went crazy and turned on him. Claymore says that the clay monsters will turn them into clay monsters too by covering them in clay.
Mabel, having run off, wonders what to do. While fiddling with loose clay, she has an idea. She dives into the Cyclops through its belly button and remolds it into Shimmery Twinkleheart, a character from Believe in Yourself, which crushes the other clay figures while Mabel frees her friends. They initially assume that Mabel conquered her fear, but Mabel explains that she's twice as scared now, but now she knows it's a perfectly rational fear.
Back at the Shack, the gang watches another Loinclothiclese movie, and Stan and the twins are glad no one got turned got turned into clay. However, they discover that Soos has turned into clay, and Stan throws the VCR at his head to get rid of him.
After that story, when the person still refuses to buy anything, Stan offers him a free sample of a "delicious potion". When they drink it, he passes out. He later wakes up trapped in a glass box, now a Mystery Shack attraction dubbed "The Cheapskate." During the end credits, he plays tic-tac-toe with Mabel, who keeps bending the rules to her advantage.
