Tourists soaking up the sun at picturesque beaches in the Netherlands are being greeted by a "strange and scary" surprise.
A series of rare and eye-catching sculptures by Dutch artist and inventor Theo Jansen are being found at various beaches.
Said to be a fun fusion of art and engineering, the "Strandbeest" are kinetic sculptures that are like skeletons ... that move.
Made from yellow plastic tubes, they can walk on their own, getting energy from the wind.
Jansen has previously said of his creations: "I make skeletons that are able to walk on the wind, so they don't have to eat. Eventually I want to put these animals out in herds on the beaches, so they will live their own lives."
