PORT ARANSAS, Texas (KXAN) — Their origins unknown, barnacle-covered dolls continue to appear along the Texas shores at Port Aransas, and researchers there are documenting it for all to see.

The first doll washed ashore in January 2021, dubbed by the Mission-Aransas National Estuarine Research Reserve as “the craziest beach find of all time.” And yet, the craziness has continued.

Researchers told the Fort Worth Star-Telegram approximately 30 dolls have been collected in over a year. The dolls arrive covered in barnacles, missing limbs and some stained green due to algae.

While crews are stationed along Port Aransas specifically for research on coastal ecosystems, they’ve added a bit of levity — and mystery — to their work, Mission-Aransas Reserve Director Jace Tunnell told the Star-Telegram.

“Every day is something new,” he said. “Just when you think you’ve found everything that could possibly wash up on shore, something else comes up.”
