Once upon a time, in a faraway land, there was a magical castle called Lullaby Castle. It was made of pink and purple candy, and it sparkled in the sunlight. The castle was surrounded by a moat filled with rainbow-colored water. Inside the castle, there lived a kind queen named Queen Melody. She had long, flowing golden hair and wore a crown made of stars.

Every night, Queen Melody would sing a beautiful lullaby that could be heard all around the kingdom. The lullaby was so soothing that it made everyone fall asleep peacefully. The castle was filled with music and happiness.

One day, a mischievous dragon named Spark came to the kingdom. Spark loved to play pranks on everyone and make loud noises. The people of the kingdom couldn't sleep because of Spark's mischief. Queen Melody knew she had to do something to help her people.

Queen Melody decided to use her magical singing powers to calm Spark down. She sang the most beautiful lullaby she had ever sung. Spark listened to the lullaby and felt a warm, peaceful feeling inside. He stopped his mischief and fell into a deep sleep.

From that day on, Spark became a friend of Queen Melody and the people of the kingdom. He promised to never disturb their sleep again. Lullaby Castle was once again a place of tranquility and happiness. Queen Melody's lullaby continued to bring peaceful dreams to everyone in the kingdom.
