For more than 30 years, author R.L. Stine’s spooky series “Goosebumps” has been scaring kids in print, and now on the screen.

“This Halloween, thousands of kids will go out as Slappy the dummy. And it’s a thrill, really,” Stine said.

The best-selling children’s book author still writes every single day, pecking away with just one finger, from his Upper West Side apartment.

“I write 2,000 words a day. I’m a machine. It’s like 10 pages. And I have a little game I play with myself. When I hit 2,000 words, I just quit, no matter where I am,” Stine explained.

Halloween is his busiest time of the year. A new “Goosebumps” series, “House of Shivers," is hitting bookshelves, and a new television show is streaming on Disney+.

In person, Stine — who goes by Bob — is the antithesis of his professional brand. He’s gentle, endearing, and comfortable right where he is.

“I love New York. I’ve been here over 50 years,” Stine said. “I came right from Ohio State to New York, and I couldn’t live anywhere else. But when my wife wants to insult me, when she really wants to insult me, she says, ‘You’ll be from Ohio for the rest of your life.’”

Stine says, however, that he doesn’t really want to terrify his readers.

“I have one rule: Kids have to know it’s a fantasy. They have to know that what happens in the books could never really happen,” he said.

That’s what Halloween is all about: the tease, the fantasy, the safe scare. So tomorrow, Stine will wake up, take his dog Lucky for a walk, and write another 2,000 words. He tells NY1 the secret to his success.

“Work. But luck, mainly luck. I just feel like the luckiest person,” he said.
