One day, a cheerful crab named Tim found a shiny shell on the beach. He was so happy because he wanted a new home. He picked up the shell and started to walk away. But then, a little fish named Finn swam up to him.
"Hey, that's my shell!" said Finn. Tim and Finn started to disagree about whose shell it was. They both wanted the shiny shell for their home. As they were talking, a big wave came and took the shell away. Tim and Finn were sad.
Then, something unexpected happened. A big, friendly whale named Willy swam up to them. He had seen the shiny shell and brought it back to them. "Here is the shell," Willy said. "But you must learn to share." Tim and Finn agreed to share the shell and became best friends. They thanked Willy and lived happily in their shared shell home.
