One sunny day, Peppa Pig was playing in the park, when she heard the distant sound of a train whistle. Excited, she decided to go watch the big train pass by.

Peppa ran to her younger brother, George, and shared the exciting news. George, holding his favorite dinosaur toy, followed Peppa towards the train station.

As they reached the station, they were amazed by the enormous train. The train was of many colors, and it was the most beautiful thing they had ever seen.

Suddenly, the big train started shaking and making loud noises. It seemed like it was in pain. Peppa and George were startled but knew they had to help.

Peppa, with George by her side, bravely approached the big train. They asked what was wrong, and the train said it was having a tummy ache due to bad coal.

Without wasting any time, Peppa and George ran to find good coal. They were determined to save the big train and prevent any disaster.

They reached a coal mine and started collecting the shiny black coals. It was hard work, but they didn't give up.

Soon, they had enough good coals. They quickly ran back to the big train, hoping they weren't too late.

Peppa and George fed the good coals to the train. Gradually, the shaking reduced, and the smoke cleared. The train was feeling better.

The big train thanked Peppa and George for their help. It was grateful and promised to be more careful with its diet.

After the intense day, Peppa and George returned to the playground. They played happily, knowing they had saved the day.

They learnt the importance of helping others in need. The day ended with the siblings sharing their adventure with their friends, becoming the heroes of the day.
