There are certain things you expect to find when you walk along the beach: colorful seashells, tufts of seaweed, or maybe even a chunk of coral reef. The ocean is home to such a thriving vibrant environment, so it’s not unusual for the sea to gift us with little bits of its beauty.

However, there have been plenty of instances where beach-goers found stuff that led to far more questions than answers. It was impossible to tell how or why some of these things washed up on shore, but they all made for one heck of a unique story.

1. Sneakers: On the Dutch island of Terschelling, citizens were startled early one morning when they discovered thousands of running shoes covering the sand. Apparently, a cargo ship lost one of its containers during a violent storm, turning the beach into an outdoor Foot Locker.

2. Piano: One afternoon, underneath the Brooklyn Bridge in New York City, someone came across a piano. Although the body was perfectly intact, it no longer played. No one ever found out who it belonged to.

3. Rubber ducks: Back in 1992, a massive shipping crate full of hundreds of thousands of rubber ducks fell overboard in the middle of the ocean, and still to this day, massive amounts of these bath-time toys still occasionally wash up on the shores of various countries.

4. Giant LEGOs: Not much is known about the Dutch painter and sculptor who calls himself Ego Leonard other than he works with large-scale fiberglass LEGO art. These oversized toys occasionally find themselves on shores all over the world.

5. Perfectly formed snowballs: A Siberian beach was found blanketed in perfectly formed snowballs in 2016. This was due to an extremely rare phenomena causing pieces of ice to roll up and then become smoothly polished by the elements. Did someone say epic snowball fight?

6. Giant eyeball: In 2012, someone came across a giant eyeball while walking along the shore in Fort Lauderdale, Florida. People naturally wanted to believe it came from some kind of undiscovered sea monster, but scientists determined it belonged to a massive swordfish.

7. E.T.: One afternoon, a person thought they saw a lifeless body floating in the shallow ocean water. Upon further inspection, it was actually a life-sized doll of E.T.! Talk about discovering something alien!

8. Bananas: In 2007, six enormous crates of bananas fell overboard from a ship traveling to Cuba. Almost all of them somehow made the long journey to the shores of Terschelling in the Netherlands. Yep, that’s right. The same place that was the recipient of those thousands of pairs of running shoes. Weird…

9. Inscribed rocks: While people were taking a stroll along a beach in Oakville, Ontario, they came across a stack of rocks with inspirational and personal messages inscribed on them. Did whoever wrote them ever find their soulmate?

10. Mechanical hand: Someone dropped a mechanical prosthetic hand into the water near Staten Island, New York, and it quickly washed ashore. Who did it belong to? Apparently, one very clumsy robot.

11. SpaceX debris: On the beach of Elbow Bay in the Bahamas, people were in shock when they found massive chunks of metal lying in the shallow waters. Where did they come from? They were pieces of one of SpaceX Falcon 9’s crashed rockets.

12. Intact shipwreck: This ship, called Navagio, is a tourist attraction in Greece. It was built in 1937 and was used to smuggle cigarettes. After it was destroyed in a massive storm while trying to flee the Greek Navy in the 1980s, it eventually washed ashore on a beach in Navagio Bay.

13. Strange gelatinous blobs: Throughout 2015, about a billion of these weird gelatinous blobs of jelly called velella washed up on west coast shores of the United States. As dramatic and bizarre looking as the incident was, marine biologists actually said it happens roughly once every three to six years.

14. Doritos: On the beaches of North Carolina one morning, a massive shipping container full of Doritos washed ashore. Thousands of bags of the popular snack were strewn all over the sand, much to the delight of the hungry beachgoers.

15. Flyswatters: In 2012, off the coast of Alaska, a cargo ship lost several crates of flyswatter with college sports teams’ insignia printed on them. Insects beware, Notre Dame is coming for you…

16. Harley-Davidson motorcycle: After a devastating tsunami hit Japan in 2011, one man’s Harley-Davidson motorcycle was swept out to sea. Incredibly, it was found 5,000 miles away on a beach in British Columbia!

17. Dead birds: Roughly 6,000 deceased waterfowl washed up on the shores of Georgian Bay in Ontario, Canada. Scientists believed they all consumed botulism-laced fish, and although die-offs of large numbers of birds isn’t extremely unusual, the number of waterfowl had scientists quite startled.

18. Drugs: In 2013, off the coast of Japan, someone found six backpacks stuffed with packages of cocaine. The total weight of the narcotics was 78 kilograms, and police estimated the find to be worth $70 million!

19.  Sea mine: When one family came upon this mystery object at the beach, they initially thought it was some kind of buoy that made its way onto the land. In reality, however, it was actually a World War II-era mine!

20. Giant pipes: Early one morning in August 2017, beach walkers in Norfolk, England, were greeted with massive sections of metal pipes. Some of them were as long as 1,500 feet and eight feet in diameter! They had reportedly broken off a Norwegian tug boat after it collided with an Icelandic container ship on its way to Algeria.

How bizarre are some these discoveries? Hey, you truly never know what you’ll find when you spend a day at the beach.
