A sculptor changes all the Gummies except for Gruffi and Grammi into statues with magic dust. Meanwhile, Gruffi and Grammi are frequently fighting and don't want to work together. King Gregor then buys the statues for Princess Calla. So it's up to Gruffi, Grammi and Cavin to turn the others back to normal. Can they do it, or will Gruffi and Grammi's arguing get in the way?

The Gummis are nearly out of Gummiberry juice so Grammi needs to make more, but the spigot is stuck so Zummi, Grammi, Cubbi, and Cavin go to the pumping station to fix the problem. But they discover that the facility is near a maritime boundary that separates Dunwyn and Drekmore – where Duke Igthorn and his ogres live. They only have four bottles of Gummiberry juice left, that's one for each of them. Can they fix the problem and get back home safely to Gummi Glen without being noticed by the ogres?

While exploring an ancient storeroom of the Great Gummis, Tummi discovers a mechanical decoy used to make dragon footprints, but accidentally starts the ignition on the machine and begins bouncing all across the land. The footprints attract a real dragon who proves to be different from the stereotype of large dragons. The knights of Dunwyn also see the machine and think it is a real dragon.

Zummi gives Cubbi a whistle from his old treasure chest while Sunni is having trouble babysitting Cubbi. The whistle attracts a brine dragon, which takes Sunni and Cubbi on an unexpected adventure to Drekmore Castle.

Sunni is kidnapped by a flock of ugly bird-like creatures known as Carpies, whose king wants her for a song bird. The Gummis (Gruffi, Zummi, and Cubbi) must use their new flying machine to get to the top of the mountain and rescue her, all whiledealing with Zummi's acrophobia and Gruffi's insistence that "Gummis were not meant to fly".

While trying to sneak out of his new diet, Tummi finds a stone ogre oracle and uses it to trick Duke Igthorn and the ogres with it.

Cavin is having problems with knight training. Cubbi suggests an underground wishing stone could be a big help, but they soon learn the stone is guarded by a mean giant. Cavin and Cubbi must find several different ways to thwart to giant, until Cavin finally realizes being a knight is not always about strength.

Zummi makes a magic hat for Sunni, which can change her appearance to anyone she wants by speaking that person's name, and Sunni turns herself into Princess Calla to enjoy the comforts of royalty. Coincidentally, the real Princess Calla is kidnapped by Igthorn while going outside Dunwyn's castle walls. When the two princess contestants meet in a Drekmore tower cell, what will happen once the true princess exerts her right of existence?

Despite Gruffi's objections, Cubbi finds a wolf cub and raises it.
