Hundreds of people have called, emailed or reached out to the Science Museum of Minnesota over social media since Friday, when the new season of “Stranger Things” debuted with a surprise local tie — a purple dinosaur sweatshirt that was sold in the 1980s at the museum gift shop.

Dustin, a spunky character in the Netflix science fiction-horror series, was seen wearing the sweatshirt in the first episode of the show’s newest season. Fans of the show and the museum have been calling to request the sweatshirt, which shows the fossil skeleton of a brontosaurus above the subhead “Thunder Lizard” with the Science Museum of Minnesota written below in white letters.

Sarah Imholte, public relations specialist for the Science Museum, said they’re working on reproducing the sweatshirts, which should be available for purchase later this week.

Imholte said she doesn’t know how the sweatshirt ended up on the show. She found out about it through Twitter.

“We just had no idea it would be included in the show,” she said, adding that the museum’s Facebook post about the sweatshirt has reached close to 300,000 people. “It went viral.”

The museum has created a signup page on its website for updates on the product.
