Oscar was walking back home from school when he saw a construction crew setting up near the city square. He noticed they had many cones and signs warning people of the ongoing construction.

As he walked closer, he spotted a bright orange cone with a friendly face and two big eyes. "Hi there!" said the cone cheerfully. "My name is Sammy. What's yours?"

"I'm one of the safety cones of this crew, and we're building a safety wall nearby," said Sammy proudly.

"That's right," Sammy replied, "It's a colorful wall with lots of safety tips and reminders for everyone to see. We want to help people remember to stay safe."

Sammy looked at him with surprise. "Of course! We could use your help. But first, we need to make sure you are safety certified."

"We need you to learn some basic safety rules, like looking both ways before crossing the road, wearing a helmet while riding a bike, and not talking to strangers," Sammy said.

Oscar nodded and started listening carefully as Sammy explained each rule in detail. After going over the rules, Sammy gave Oscar a safety certificate, and he was ready to help.

Oscar and Sammy were now part of the construction crew. They arrived at the site where the safety wall was to be built and saw a vast, blank wall. The crew started with a plan, and Sammy put Oscar in charge of painting some safety symbols on the wall.

As Sammy and the other crew members were fixing the wall, Oscar began drawing. He painted a bicycle symbol, a pedestrian symbol, and a car symbol to remind people to be cautious while driving or walking.

Suddenly, a gust of wind blew and knocked over the paint can. The paint spilled and splashed all over the wall and Oscar's clothes.

Sammy rushed over and saw the mess. "Don't worry, Oscar. We'll fix it. We'll use some damp cloths to wipe it off, and we'll start again," Sammy reassured him.

But when they tried to wipe off the paint, the colors started to mix, and the wall began to look like a big mess. Oscar was heartbroken and felt like he had ruined everything.

"Sammy, I am so sorry. I ruined everything. I don't know what to do," Oscar said, tears forming in his eyes.

Sammy put his hand on Oscar's shoulder. "Don't worry, Oscar. Accidents happen, and we can always fix them. Let's just think of a new idea for the wall."

Oscar felt relieved and moved away from the wall to think. As he moved, he saw a group of kids passing by. They stopped and looked at the wall, which was now a colorful mess.

Oscar listened to their conversation, and an idea struck him. "Sammy, I've got it!" he exclaimed.

"We can make the wall into a puzzle! That way, people will have to think about each piece to find the safety message behind it," Oscar said, excitedly.

The rest of the crew agreed, and together, they painted different safety symbols and messages on the wall. They made it into a colorful puzzle, and the kids were delighted to solve it. Even adults could not resist the wall's charm and stopped to admire it, reading each message carefully.

The puzzle safety wall was an instant hit! People loved it so much, they started taking pictures with it and sharing them on social media. The city's mayor even came to see it and congratulated the crew on their excellent work.

"Sammy, you and your crew have outdone yourselves," said the mayor. "This wall has become a landmark for our city, and it's all thanks to your team's creativity."

Sammy and the crew beamed with pride, and Oscar knew he was part of something special.

"Thanks, Oscar, for your great idea. It saved the day," Sammy said, giving him a high-five.

Oscar felt happy, knowing he had helped make something special and worthwhile. The safety wall was now more than just a wall - it was a symbol of how honesty, hard work, and creativity can overcome any challenge.
