Almost five million bits of Lego were lost at sea in 1997, when a huge wave hit the container ship the Tokio Express and washed 62 containers overboard. In Cornwall, England, shipwrecked Lego pieces still wash up daily.
Tracey Williams, British writer and beachcomber, has devoted a Facebook page to the lost Lego pieces - which ironically were mostly sea related. Tiny spear guns, seagrass, and Lego scuba gear wash ashore.
Lego pieces also wash on shore in Devon, Ireland and Wales. There's speculation that the pieces have travelled around the world by now, but no hard proof.
Williams, who collects the washed up Lego pieces, has gone beachcombing in Florida, but the Legos she finds aren't the ones she's hoping to find. "It's all local stuff kids have left behind," she told BBC News.
