Jollywood holds the Heroes' Day Concert in celebration of the founding fathers of the kingdom's triumph over an evil warlock that ruled many years ago. Queen Delightful commissions Happy to compose and conduct a musical piece titled "The Jollywood Jam" to be performed at the Jollywood Bowl with the rest of The 7D as the musicians. Upon hearing the news, Hildy brought her husband Grim a present—an all-too-powerful wand that can also read the mind of any person and making it come true. She then plans to ruin the kingdom's celebration with the wand and eventually rule Jollywood. Backstage at the Jollywood Bowl, the queen and Lord Starchbottom are worried that the dwarfs aren't going to make it on time and Squire Peckington was sent out to find and remind them that they're running late.
On their cart, the Glooms (dressed as tourists on vacation) are on their way with their pig Peaches who's wearing roller skates (probably this time around they've realized how unreliable Peaches is because of her extremely slow speed). At the crossroads, The 7D's oncoming speeding cart crashed into the Glooms. Two wands were swapped in the air: Happy now have in his possession the Glooms' powerful wand, while the Glooms gained Happy's conducting baton. The dwarfs finally arrived at the venue and proceeded to take their places. Hildy and Grim then showed up and tried to cast a spell at Happy, but nothing happened. They still don't know that they have his baton.
Happy begins the musical performance unknowingly that he's conducting with the powerful wand. Suddenly, the 7D were taken into many different environments magically—a wooden horse race, video game, and surfing at the ocean among them—wowing the audience amid a confused Starchbottom. Sir Yipsalot notices the Glooms' attempt to retrieve their wand. He then caused the baton to be swapped back to Happy and the wand to Sir Yipsalot. The performance ends with fireworks resembling each of The 7D, Sir Yipsalot, Queen Delightful, and Lord Starchbottom. The Glooms chased the dog into the woods; with the wand in mind reading mode Sir Yipsalot's thinking about pickles, his favorite snack. A large pile of pickles stopped the Glooms in their tracks, then they became cats.
The queen commended the dwarfs for putting on a great show. Starchbottom suggested that he could have the dwarfs on a roadshow, but Grumpy isn't fond of the idea because his tuba playing always made his lips very numb.
