Jacob and Ella lived in a big apartment building in the Bronx. Their neighbor, Mr. Walker, was a car mechanic with a secret. He always carried his fishing gear with him and smelled like fish. One night, a strange smell came from Mr. Walker's apartment.

Curious, Jacob and Ella decided to investigate. They sneaked into Mr. Walker's apartment, but it was empty. Then they went to his mechanic shop, filled with tools and cars. They found a map with fishing spots.

Following the map, they arrived at a hidden pond nearby. Mr. Walker was there, fishing. They discovered a hidden cave next to the pond. Inside, they found a glowing artifact. They realized it was the source of the strange smell.

Mr. Walker explained that the artifact was a magical amulet. It had powers to attract fish, but it also gave off a mysterious smell. Mr. Walker promised to keep it safe and thanked Jacob and Ella for uncovering the secret. From then on, they had exciting adventures with Mr. Walker and his fishing gear.
