The wax figures were a group of cursed wax sculptures that appeared in the Gravity Falls episode "Headhunters". Cursed to come to life when the moon is waxing, the figures took on the character traits of the individuals and characters they were made to resemble.
Many years before the events of the series, the wax figures were on display at a yard sale (in a graveyard). Stan Pines took an interest in the figures, but rather than pay $20 for the set, he decided to simply steal them. For some time, Stan put the figures on display in the Mystery Shack and during the night the figures would come to life and hang out. Eventually, Stan's customers lost interest in the wax museum and Stan locked the figures away. The figures remained in storage for ten years, plotting to take revenge against Stan.
Ten years later, Soos stumbled upon the door to the storage room where the wax figures were kept. Dipper and Mabel see the figures and find that one of them has melted after a blind was left open, letting the sunlight in. Mabel decides to use the molten wax to make a new sculpture of Grunkle Stan and the wax figures are unveiled to the public the next morning, but due to false advertising circulated by Stan, the crowd leaves soon after. That night, after the real Stan leaves momentarily to use the bathroom while he is watching television with his wax counterpart, Wax Sherlock Holmes comes to try to avenge himself and the other figures by decapitating Stan, but ends up beheading the wax version. After the twins' search for Wax Stan's "murderer," they attend the statue's funeral, and come to the conclusion that it was the other figures.
The figures then sarcastically and condescendingly congratulate them for solving the case, and they proceed to tell the children their backstory. Then, they decide to try and kill the Pines twins and their uncle, and the battle to the death begins. After the kids stumble upon their foes' weakness (heat), they use coffee and candles to melt their enemies. While Mabel takes on the majority of them, Dipper engages in a one-on-one sword fight with their leader, Sherlock Holmes, whom he defeats by leading outside in the sun. Meanwhile, Mabel burns all the wax figures, except Larry King's head, in the fireplace. The head observes the Pines as he hides in the vents, and soon must chase after a rat that steals his ear. In the credits, he is seen helping Mabel choose which sweater to wear.
List of wax figures
- Sherlock Holmes - The ringleader of the wax figures, based on the fictional character created by Sir Arthur Conan Doyle. He fights with Dipper in the Mystery Shack and eventually on the roof.
