"I had someone go to shake my hand like this, and he shook my hand, and he pulled it, and licked my hand," 15-year-old Matarazzo told Variety.
"And then they just looked at me for like a good thirty seconds. And he said, 'can I get a picture?' I said, 'you licked me.' And then like, 'yeah,' like it was totally normal. I'm like, 'I think I better go.' That's not healthy."
"I've had a couple," 13-year-old Schnapp said. He explained, "I mean, one time I was in the bathroom, peeing at a urinal, and then the guy just came over — I think he, like, followed me into the bathroom."
"Then he just like tapped me on the shoulder. I was like, 'oh, uh, I'm peeing right now.' And he asked for a picture. It was a little awkward."
Their 15-year-old co-star Finn Wolfhard took to social media in November asking fans to stop harassing his teenage cast mates, who have been in the public eye since the Netflix original series became a pop culture phenomenon in 2016.
The Stranger Things kids — Wolfhard, Matarazzo, Schnapp, and 16-year-old Caleb McLaughlin and 13-year-old Millie Bobby Brown — are among Hollywood's most recognizable young faces for their roles in the series, which has tapped into the cultural zeitgeist as much as contemporaries Game of Thrones and The Walking Dead.
Wolfhard most recently starred in Warner Bros.' big screen horror hit IT, while Brown will make her movie debut in next summer's Godzilla: King of Monsters.
Netflix debuted Stranger Things 2 in October, adding 15-year-old Sadie Sink to the group as newcomer Max.
All six actors are expected to return for the next round of eerie happenings to come out of the sleepy town of Hawkins, Indiana in the third season of Stranger Things, hitting the streaming service sometime in 2019.
Both seasons of Stranger Things are now available for streaming on Netflix.
