Calvin meets the Gummi Bears and asks if they will help stop Duke Igthorn from destroying Castle Dunwyn.

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?

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.

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.

A bird threatens the Gummiberry bushes and nobody will listen to Cubbi's ideas to get rid of it.

Grammi believes it is time to teach another Gummi Bear how to make Gummiberry juice. Sunni is chosen as the most eligible candidate, but is more into fashion and spending time with Calla. The Ogres kidnap Grammi and take her to Castle Drekmore, where Duke Igthorn attempts to coax the recipe for Gummiberry juice from her. When the Gummis go on a rescue mission, they request Sunni to follow and bring some Gummiberry juice, which Sunni does not know how to make because she failed to pay attention to Grammi's lessons.

The Gummies try to sweeten Gruffi's sour disposition by magic, but the conditions of the spell they use turn this affair into a two-edged sword.

Tummi learns through his new friend, the blind shepherd Trina, that handicapped people are not helpless.

Sunni finds a baby cliff dragon with a hiccup, and a swig of Gummiberry juice only aggravates the problem.

The Gummies find a Gummiscope, a gigantic machine that harnesses sunlight as a means of long-range communication, that could allow them to make contact with the Great Gummis across the ocean – but it can also be used as a weapon, causing Duke Igthorn to use it as a laser-type weapon to force King Gregor into surrender.
