Harv was a clever boy who knew about trolls, and so as soon as he knew that they had been locked up inside the Dark Castle by their wicked stepmother, he told Nell that they must go out and gather all the firewood they could find.

Rummaging in the Great Hall of the castle, he found a suit of armor holding a battle-axe. "I will chop down some trees with this," he said, "and you must go out and gather kindling."

"What's kindling?" Nell asked.

An illustration of the castle appeared. In the center was a tall building with many towers that rose up into the clouds. Around it was an open space where trees and plants grew, and around that was the high wall that held them prisoner.

The illustration zoomed in on an open grassy area and became very detailed. Harv and Nell were trying to build a fire. There was a pile of wet logs Harv had chopped up. Harv also had a rock, which he was striking against the butt of a knife. Sparks flew out and were swallowed up by the wet logs.

"You start the fire, Nell," Harv said, and left her alone.

Then the picture stopped moving, and Nell realized, after a few minutes, that it was fully ractive now. She picked up the rock and the knife and began to whack them together (actually she was just moving her empty hands in space, but in the illustration Princess Nell's hands did the same thing). Sparks flew, but there was no fire.

She kept at it for a while, getting more and more frustrated, until tears came to her eyes. But then one of the sparks went awry and landed in some dry grass. A little curl of smoke rose up and died out.

She experimented a bit and learned that dry yellow grass worked better than green grass. Still, the fire never lasted for more than a few seconds.

A gust of wind came up and blew a few dry leaves in her direction. She learned that the fire could spread from dry grass to leaves. The stem of a leaf was basically a small dry twig, so that gave her the idea to explore a little grove of trees and look for some twigs. The grove was densely overgrown, but she found what she was looking for beneath an old dead bush.

"Good!" Harv said, when he came back and found her approaching with an armload of small dry sticks. "You found some kindling. You're a smart girl and a good worker."

Soon they had built up a roaring bonfire. Harv chopped down enough trees to make sure that they could keep it going until sunrise, and then he and Nell fell asleep, knowing that trolls would not dare approach the fire. Still, Nell did not sleep very well, for she could hear the mutterings of the trolls off in the darkness and see the red sparks of their eyes. She thought she heard another sound too: muffled voices crying for help.

When the sun came up, Nell explored the Dark Castle, looking for the source of the voices, but found nothing. Harv spent the whole day chopping wood. The day before, he had cut down a third of the trees, and this day he cut down another third.

That night, Nell again heard the voices, but this time they seemed to be shouting, "Look in the trees! Look in the trees!"

The next morning, she went into the remaining grove of trees and explored it even as Harv was cutting the last of them down. Again she found nothing.

Neither one of them slept well that night, for they knew that they were burning the last of their wood, and that the next night they would have no protection from the trolls. Nell heard the voices again, and this time they seemed to be shouting, "Look under the ground! Look under the ground!"

Later, after the sun came up, she went exploring again and found a cave whose entrance had been shut up by trolls. When she opened the cave, she found four dolls: a dinosaur, a duck, a rabbit, and a woman with long purple hair. But she did not see anything living that could have made the voices.

Nell and Harv went into the Dark Castle itself that night and shut themselves up in a room high in one tower and pushed heavy furniture against the door, hoping that it would keep the trolls at bay. The room had one tiny window, and Nell stood next to it watching the sun go down, wondering if she would see it rise again. Just as the last glimmer of red light disappeared beneath the horizon, she felt a puff of air at her back and turned around to see an astonishing sight: The stuffed animals had turned into real creatures!

There was a great scary dinosaur, a duck, a clever little bunny rabbit, and a woman in a purple gown with purple hair. They explained to Princess Nell that her wicked stepmother was an evil sorceress in the Land Beyond, and that the four of them had long ago sworn to defeat her evil plans. She had placed an enchantment on them, so that they were dolls in the daytime but returned to their normal selves at night. Then she had imprisoned them in this castle, where the trolls had shut them up inside a cave. They thanked Nell for releasing them.

Then Nell told them her own story. When she mentioned how she and Harv had been plucked from the ocean wrapped in cloth of gold, the woman named Purple said, "This means that you are a true Princess, and so we pledge our undying loyalty to you." And all four of them bent down on one knee and swore an oath to defend Princess Nell to the death.

Dinosaur, who was the fiercest of them all, mounted a campaign to stamp out the trolls, and within a few days they had all been driven away. Thereafter Nell was no longer troubled in her sleep, for she knew that the scary trolls, who had once given her bad dreams, had been replaced by her four night friends.
