You might enjoy finding shells and sea glass on the beach but what about Lego?
Well in Cornwall you could find some.
In 1997 a goods container filled with millions of Lego pieces fell off a ship and into the sea.
Since then hundreds of pieces have washed up on the beaches of Cornwall.
Ayshah went to a beach in Cornwall to meet some local kids who have discovered Lego there.
See how she got on when she went on a hunt for some of her own.
