In 1997 a shipping container filled with 4.8 million Lego pieces fell from a cargo ship off the coast of Cornwall in southern England.
The BBC reports that pieces are still floating to shore 17 years later.
The Tokio Express captain described the wave that hit the ship as a "once in a 100-year phenomenon." The ship tilted 60 degrees one way, then 40 degrees back, sending more than 60 containers into the water.
Tracey Williams has started a Facebook page to track the Lego pieces. Take a look at some of what's washed ashore.
