The nature-talent fairies are bringing to the mainland the season of leaves, hibernation, chilly breezes, and pumpkins: autumn. Meanwhile, Tinker Bell and dust-talent fairies like Terence are staying in Pixie Hollow. Tinker Bell is trying to make a "Pixie Express". But it fails just as she is called to meet Queen Clarion, Fairy Mary, and Redleaf, the Minister of Autumn.
They show her a mystical moonstone and explain to her its tremendous powers. Every eight years, there is a blue harvest moon in Pixie Hollow. When the light of this rare blue moon passes through the moonstone, it creates blue-colored pixie dust to strengthen and rejuvenate the pixie dust tree. The Autumn Revelry is the associated event during which the fairies gather to collect the dust.
A new scepter is to be made to raise the moonstone, and Tinker Bell has been recommended. Although Tinker Bell has made mistakes in the past, Fairy Mary explains that tinker fairies learn from them, most of the time. Tinker Bell accepts the task, as well as help from Terence. But as the work on the scepter progresses, Tinker Bell begins to have trouble with Terence, who is trying too hard to be helpful.
When Terence brings a compass to her workshop, Tinkerbell loses her temper and kicks it, causing it to smash her newly completed scepter. After fighting with her friend, Tinker Bell's furious antics cause her to break the moonstone as well. Tinker Bell sets out on in a balloon she's created to find a magic mirror, which, according to legend, granted two of three wishes before becoming lost. Tinker Bell intends to use the third and last wish to restore the shattered moonstone to its original form.
While trying to evade a hungry bat, Blaze crash lands into Tinker Bell's balloon, though the pixie fails to notice. After flying further, Tinker Bell begins to get hungry but when she looks through her food pouches, she finds that they've all been eaten by a firefly. Tink orders the firefly too leave, which he seemingly does, though he truly wanted to tag along with Tink on her quest to find a magical mirror that can grant one wish. Tink hopes to use the wish to repair the shattered moonstone that will provide blue pixie dust for the fairies. After Blaze's apparent exit, Tink tries to read her map but it's too dark to see. Blaze then sheds light on the map to help Tink, and the tinker finally allows him to stay. As the duo's adventure continues, Tink thinks she has stumbled upon the stone arch that is said to lead way to the mirror. She leaves the balloon to make sure of this, and leaves Blaze to watch over things. While Tink was out however, the balloon began to stray away, and Blaze rushes to tell Tink. Tink was too busy trying to figure out why she stumbled upon a bent tree instead of the stone ark, to notice Blaze. When she finally sees the balloon floating off, she briefly blames Balze. The two follow after it but the harsh winds knocks them down. The next morning, Tinker Bell awakens and is hungry and lost.
Blaze scouts out to rally some forest insects that provided food and water for Tink. They also lead her and Blaze to the stone arch, and the adventure continues. They find the shipwreck that is said to house the mirror and head inside Tinker Bell finally discovers the mirror, but she accidentally wastes the third wish.(wishing Blaze to be quiet for one minute) She got furious at Blaze and blames him, but she begins to cry. She is found by Terence, who has been following her after discovering her plans and the fragments of the moonstone in her empty house. They were chased by rats.
Tinker Bell and Terence start back to Pixie Hollow. Along the way, Tinker Bell fixes the scepter using a white gem from the top of the mirror, the scepter pieces Terence has wisely brought, and the moonstone pieces, all set at just the right angle. She discovers the magic of true friendship, humility and love. Thanks to inspired teamwork with Terence, she is ready to give the scepter to Queen Clarion.
When she unveils the scepter, the assembled fairies are all shocked and alarmed to see the fragments of the precious moonstone. However, the broken moonstone shards create an unexpected benefit: they drastically magnified and increased the surface area through which the rays of the blue moon could pass, creating the largest supply of blue-colored pixie dust ever seen in Pixie Hollow.
THE END.
