Tom and Mia like to play with their toy cars. They have many cars of different colors and sizes. They make roads with chalk on the sidewalk and pretend to drive around.
One day, they find a big oak tree in the park. The tree has many leaves and acorns. Tom and Mia think it is a good place to park their cars. They drive their cars under the tree and line them up.
"Look, Mia, we have a car lot!" Tom says. "We can sell our cars to other kids."
"OK, Tom, but I want to keep my pink car. It is my favorite," Mia says.
They sit under the tree and wait for customers. Soon, a boy comes by with a bike. He sees the cars and stops.
"Hi, I like your cars. Can I buy one?" he asks.
"Sure, you can buy one. They are two cookies each," Tom says.
The boy looks at the cars and picks a blue one. He gives Tom two cookies and takes the car.
"Thank you, bye!" he says and rides away.
Tom and Mia are happy. They have cookies and cars. They eat one cookie each and save the other for later.
They play with their cars some more. They make noises and honk their horns. They have fun.
But then, Mia makes a mistake. She drives her pink car too fast and hits a rock. The car flips over and rolls away. Mia is sad. She runs after her car.
"Tom, help me! My car is gone!" she cries.
Tom hears Mia and sees her car. It is rolling down a hill. He runs after it too.
"Mia, wait! I will get your car!" he shouts.
They chase the car down the hill. The car goes faster and faster. It is too far for them to catch.
But then, the car hits a bump. It flies in the air and lands on its wheels. It starts to roll back up the hill. It is going in reverse!
Tom and Mia are surprised. They stop running and watch the car. The car comes back to them. It stops near their feet.
"Wow, look, Mia! Your car came back!" Tom says.
Mia is happy. She picks up her car and hugs it.
"Yay, my car came back! It is a magic car!" she says.
Tom and Mia smile. They hug each other and their cars. They go back to the oak tree and play some more. They are careful to drive slow and avoid rocks. They have a good day.
