The Three Billy Goats Gruff
"The Three Billy Goats Gruff" is a Norwegian fairy tale about three goats who want to cross a bridge to reach a meadow full of grass. The goats are named Billy Goat Gruff, and they are different sizes: the smallest, the middle-sized, and the largest. Each goat encounters a troll living under the bridge who threatens to eat them.
The smallest goat crosses first and convinces the troll to wait for the bigger goat. The middle goat follows, using the same tactic. Finally, the largest goat confronts the troll and defeats him, allowing all three goats to cross the bridge safely and enjoy the meadow.
