Periwinkle raced through the Winter Woods ahead of Dewey. The elderly fairy was doing his best to keep up with her, but the blustery wind was strong and made it difficult for him to fly.

“Dewey, you gotta see this!” Periwinkle called.

“I’m sure there’s nothing to worry about!” Dewey assured her. But as they reached the place where Periwinkle was taking him, he stopped short. “Oh, dear,” he said.

Periwinkle joined her friends Gliss and Spike at the edge of the Pixie Dust Well. Normally, there would be a steady stream of pixie dust flowing from the root above it. But there was no flow of pixie dust now. There was nothing—not even a trickle.

“There must be something wrong with the Pixie Dust Tree,” Periwinkle said.

Dewey examined the hollow root and tapped his cane on it. One last speck of dust fell into his palm. He furrowed his brow. “Yeah, you might want to worry just a little bit,” he said.

At that moment, Periwinkle’s wings began sparkling.

“Tink?” she asked in shock. Periwinkle flew up and looked out over the white landscape. On the horizon, racing straight toward them, was Tinker Bell! She was carrying her winter coat so that her wings were exposed and she could fly. But they were quickly icing over.

“Periwinkle!” Tink shouted. She fought against the freezing gusts that whipped past her. There was no time to lose. Tink had to reach her sister. All of Pixie Hollow was counting on her! But the cold was just too strong. Before she could get there, Tinker Bell fell to the ground in a heap.

“Tinker Bell!” Periwinkle cried. She, Dewey, and her friends rushed to where Tink had fallen.

Meanwhile, Tink lifted her head from the snow. Something was wrong. She looked back at her wings and gasped. They had turned ice blue! Quickly, she hid them under her coat so Periwinkle wouldn’t see how cold they had become.

Periwinkle and her friends helped Tink sit up. “Are you okay?” Periwinkle asked, her face filled with concern. “Why would you fly here?”

“I had to,” Tink panted. “Pixie Hollow’s in trouble. There’s a freeze, and the Pixie Dust Tree is in danger.”

Dewey looked at the winter fairies. “That explains it,” he said.

A terrible feeling formed in Periwinkle’s stomach. “Our dust here…it already stopped flowing,” she said.

Tink handed them the blue periwinkle flower she’d brought with her. “I think there’s something you can do,” she explained. “Your frost…it kept the flower alive.”

Gliss stepped forward. “Frost does that. It’s like a little blanket. It tucks the warm air inside and keeps out the cold.”

Periwinkle’s eyes grew wide. “We could frost the Pixie Dust Tree before the freeze hits it!”

Tinker Bell smiled. She had known that her sister would understand.

But Spike seemed doubtful. “What about our wings?”

Dewey shook his head. “If it’s a freeze, it will be cold enough to cross.”

The fairies all looked at one another.

“Then what are we waiting for?” Spike asked.
