Boris was sitting in her room, staring out the window, thinking of all the things she wanted to do this summer. Suddenly, her mom walked in with a piece of paper in her hand.

"Boris, look what came in the mail today!" her mom exclaimed, holding out the paper for Boris to see.

Boris looked at the paper and read, "The Water Conservation Fair in Home! Join Wally the Water Drop and learn about saving water. Fun games and activities for the whole family!"

Boris was excited. She loved learning about the environment and how to take care of it. She quickly made plans to attend the fair with her family.

The day of the fair arrived, and Boris and her family were some of the first people through the gates. The fair was decorated with colors of blue and green, and there were water droplets everywhere.

Boris spotted Wally the Water Drop in the middle of the fair, surrounded by children. Wally was teaching the children about the importance of saving water through fun games and activities. Boris couldn't wait to join in.

Boris and her mom made their way to Wally's booth, but something was different. Instead of the usual smiles and laughter, there was a sense of urgency in the air.

"We've just received news that there's a water crisis in the neighboring town. They're running out of water, and we need to act fast," the organizer replied.

Boris' heart sank. She knew how important water was, and the thought of people not having access to it made her feel sad.

Wally saw Boris and her mom and called out to them. "Hi Boris, Hi there. I'm glad you made it to the fair. But as you can see, we have a problem. Our friends in the neighboring town are facing a water crisis."

Wally thought for a moment and then said, "I have an idea. What if we get everyone here to pledge to save water? We'll collect the pledges and send them to the neighboring town to show them that we stand with them."

Boris and her mom nodded in agreement, and they set to work, with Wally leading the charge. They went around the fair, asking people to pledge to save water, and before long, they had collected hundreds of pledges.

Just as they were about to leave, Wally looked up and saw something in the sky. It was dark clouds, and they were heading towards Home fast.

"We need to hurry," Wally said. "A storm is coming, and we need to make sure our water supply is safe."

Boris and her mom helped Wally move his water tank to a safe spot, and they covered it with a tarp. They had just finished when the rain started to pour down.

As they stood under a shelter, they watched as the water flowed down the streets, carrying with it trash and debris. Boris knew that the water crisis in the neighboring town was only going to get worse.

But they had made a difference. They had collected hundreds of pledges to save water, and they had done their part to help.

Suddenly, there was a shout from the crowd. "Look, the rain has stopped, and the sun is out again!"

Everyone looked up and saw a beautiful rainbow in the sky. Boris smiled and knew that things were going to get better.

Wally looked at Boris and said, "You did a great job today, Boris. You're a true water hero!"

Boris blushed and smiled. She knew that she had made a difference, and that was all that mattered.

From that day on, Boris made a pledge to be a water hero every day, by conserving water at home and encouraging her friends and family to do the same.

And Wally continued his mission to educate and inspire children to save water, one drop at a time.

Together, they had made a difference, and as Boris looked up at the rainbow in the sky, she knew that she had played a small part in making the world a better place.
