Long, long ago there was a poor girl called Polly who lived next to the beach.  She had a strange, little cottage with a rusty bike but she was happy. Early one morning, Polly went for a walk to collect shells. She collected flat shells, curved shells and thin shells.

Suddenly, Polly found the most beautiful shell she had ever seen, lying next to a rock pool! Slowly, Polly bent down to pick up the shell, which was glistening in the sun. To her amazement the shell spoke.

“I will grant you two wishes so choose wisely!” said the magnificent shell.
