But before long, he noticed something terrifying—a giant troll and a smaller one chasing after him!

The boy panicked, realizing the troll’s long strides would soon catch up. “What do we do, Búkolla?” he asked.

“Pull a hair from my tail and drop it on the ground,” Búkolla replied. He did as she said, and Búkolla spoke to the hair:

“Become a river so wide that only a bird can cross it.”
Immediately, a massive river appeared between them and the trolls. The larger troll, undeterred, ordered the smaller one, “Go fetch my father’s giant bull!”

The smaller troll rushed off and returned with a huge bull, which drank up the entire river in a single gulp.

The boy’s heart raced as the trolls closed in. “What now, Búkolla?”

“Take another hair and drop it,” she said. Once he did, she proclaimed, “Become a flame so high that even a bird cannot fly over it!”

A wall of fire erupted before them. But the trolls were persistent. The larger troll commanded, “Fetch my father’s bull again!” The smaller troll fetched the bull, which spat all the water it had drunk from the river onto the flames, extinguishing them.

Once again, the boy asked, “What do we do, Búkolla?”

“Take one more hair and drop it,” Búkolla instructed. “Now, become a mountain so tall that nothing but a bird can cross it.”
