Ben and Mia are friends. They like to play in the park. One day, they see a big house with a red roof. They want to go inside and look.
"Can we go in?" Mia asks Ben.
"I don't know. Maybe it is not safe," Ben says.
"But it looks so nice. Maybe there are toys and candy inside," Mia says.
They walk to the door and knock. No one answers. They try to open the door. It is not locked. They go inside.
The house is very dark and dusty. There are no toys or candy. There are only old things and spiders. Ben and Mia are scared.
"Let's go out," Ben says.
"Wait. I see something on the wall. It is a number," Mia says.
She points to a big black number on the wall. It is a six.
"What does it mean?" Ben asks.
"I don't know. Maybe it is a clue," Mia says.
They look for more numbers on the walls. They find a four, a nine, and a two.
"Maybe we can make a word with the numbers," Mia says.
She tries to say the numbers like letters. She says, "Six, four, nine, two. Six, four, nine, two."
Ben listens. He thinks he hears a word.
"I know what it is. It is a word. It is 'roof'," Ben says.
"Roof? Why roof?" Mia asks.
"Maybe it is a hint. Maybe we have to go to the roof," Ben says.
They look for stairs to go to the roof. They find them and climb up. They open a door and see the sky. They also see a big cake on a table. The cake has candles and a sign. The sign says, "Happy Birthday, Ben and Mia!"
Ben and Mia are surprised. They look at each other and smile.
"It is our birthday! We forgot!" Ben says.
"Someone made us a cake! It is so sweet!" Mia says.
They hear a voice behind them. It is their mom and dad. They are holding balloons and gifts.
"Surprise! We made you a treasure hunt for your birthday. Did you like it?" Mom says.
"We loved it! Thank you, Mom and Dad!" Ben and Mia say.
They hug their parents and eat the cake. They are very happy. They have the best birthday ever.
