It is the forty-fifth episode in the series.
The 7D invent a new dance craze that sweeps Jollywood and the entire Enchanted Forest.
The episode opens on the 7D, Queen Delightful, Lord Starchbottom, and Sir Yipsalot strapped on a huge rocket that's about to send them far away, with Hildy and Grim as the masterminds. The dwarfs and Delightful begin to recount the story of how they got themselves into that predicament. One day at her castle, the Queen wanted ice for her drink, so Doc invents a machine that makes ice cubes, called the Chilly-Frosty-Icey-Thingamacube. But the machine went haywire, and some of the cubes landed inside Grumpy's pants, causing him to react. Delightful misinterprets Grumpy's reaction to the ice cubes in his pants as a dance, and soon The 7D creates a dance around it. The 7D Dance becomes an instant sensation, and in return the dwarfs receive endorsements and Starchy even becomes their manager by request of the Queen.
As the dance craze takes over Jollywood, meanwhile, the Glooms are at night modifying Delightful's favorite outdoor meditation spot by creating a disguised hole that would send Delightful to the center of Earth if she sits on it. The Queen arrives at her spot as the Glooms went into hiding. But before she does her meditation, she uses the Bing-Bong Bell to call upon The 7D to again perform the dance for her. After Delightful and the dwarfs leave, Hildy is very annoyed about the goofy dance, though Grim enjoys it. Without any thought, she foolishly sits on the spot and she went down to the Earth's core!
Hildy is so irritated about the dance that her next plan is to end the craze once and for all. The next afternoon, she and Grim, disguised as tour guides, invited The 7D, Delightful, Starchy, and Sir Yipsalot on a magical ride on a steam-powered bus. As night falls, the bus reveals itself to be a giant rocket, and our heroes are stuck on their seat belts. As the rocket travels out of Jollywood, Hildy declares herself queen to the Jollywood villagers, and forbids anyone to do The 7D Dance ever. But the villagers misheard it as doing the dance again, and so they did. Doc redirects the rocket back to Jollywood, and everyone jumped off of it safely; and as the Glooms try to get away from it all, they came in contact with the rocket and they zoomed away from the village.
