One day, a girl named Lily and her dog, Max, went to play outside. They saw a big, round thing in the sky. It was a planet, but it was unknown to them. Lily and Max wanted to go there.
Lily said, "Max, let's build a big thing to take us to the unknown planet!" Max barked and wagged his tail. They worked hard and made a big thing out of boxes and sticks. When it was done, they got in and said, "Up, up, up!" The big thing did not move.
Just then, a friendly alien named Zara came down from the sky. She said, "Hello, I am from the unknown planet. I can help you go there. But first, we must order some special fuel." Lily and Max were excited.
Zara used her phone to order the special fuel. When it came, they put it in the big thing. Then, they all got in and said, "Up, up, up!" This time, the big thing went up into the sky. They went to the unknown planet and had a fun day playing with Zara and her alien friends.
At the end of the day, Zara said, "It's time to go home now." Lily and Max were sad, but they knew they had to go. They said goodbye to their new friends and went back to Earth. They were happy because they had a great adventure and made new friends.
