Once upon a time, in the bustling city of Mumbai, there lived a young mermaid named Mira. She loved exploring the deep blue sea.

One day, while chasing a shiny fish, Mira got caught in a strong current and was swept away far from the sea, into a strange new world.

Mira found herself in a loud, crowded place full of huge moving creatures she had never seen before: the trains of Mumbai!

Feeling scared, she hid behind a pile of old newspapers, wondering how to get back to the sea. She missed her family.

Just then, a kind boy named Raju spotted her shimmering tail. He approached her gently, offering his help.

"Don't worry, I'll help you find your way back," said Raju, noticing Mira's distress.

With Raju's help, Mira cleverly disguised her tail and they navigated the maze of platforms, seeking a path to the sea.

They had to dodge many curious eyes, but the bustling crowd was too busy to notice a mermaid in their midst.

Raju shared fascinating stories of the city's trains, and Mira listened with wide-eyed wonder.

Their journey was long, and as they traveled, Mira and Raju became good friends, laughing and sharing stories.

Finally, they heard the sound of waves crashing. Mira's heart leaped with joy - the sea was close!

With a tearful goodbye, Mira thanked Raju and promised to visit. She slipped into the water, back to her undersea home.
