Once upon a time, on a busy city street, there lived two very important friends: Mrs. Stop, the red traffic light, and Mr. Go, the green traffic light. Mrs. Stop helped the cars stop. Mr. Go helped the cars go safely. And nearby was their good friend, Superhero Sam, who always helped everyone.

One day, Mrs. Stop got tired of standing still on the traffic light. So she quietly climbed down. She walked along the road and found two bright red cherries. She put them on her ears like funny earrings and smiled proudly.

Then Mrs. Stop found a big red tomato.She started to play with it.
 But suddenly—splat!The tomato fell on her head and covered her in red juice!

At the same time, back at the traffic light, everything became mixed up. The cars were beeping.The people were confused. No one knew what to do! Luckily, Superhero Sam understood what had happened. He ran quickly, found Mrs. Stop, and said: “Mrs. Stop, your place is on the traffic light! You help everyone stay safe!”Sam took Mrs. Stop back to her place, and everything was safe again.
