Artist Nuri Durr is giving Hey Arnold! a revival — with <Nickelodeon's blessing or not.

Back in 2000, Craig Bartlett wrote a pilot script with Michelle Lamoreaux called The Patakis, a spin-off of the beloved Nickelodeon series Hey Arnold!, which found the characters in their hormonal teenage years navigating life in New York City.

Nickelodeon ultimately passed on the pilot, deeming the material "too dark" for its intended audience.

But it wasn't too dark for Atlanta-based artist Nuri Durr. As a kid, Hey Arnold! was his favorite Nicktune, so the missed opportunity for a spin-off hit him hard. Durr finally resolved his disappointment by creating a series of Hey Arnold! drawings depicting the characters as 20-somethings.

It's not a television series by any means, but the intricate and whimsical drawings in the series Yo, Pataki! certainly lay out the groundwork.

"I liked the idea of a more mature 'Hey Arnold' spin-off that focused on Helga," Durr told Mashable. "So I thought it would be fun to try and expand on Craig Bartlett's original idea in my own way."

Durr said that some of the decisions behind the characters' backstories in the series are direct references to The Patakis, while the rest are references to original Hey Arnold! episodes.

"I've always felt I could identify with the characters of Hey Arnold! on a personal level," Durr said. "Of all the characters, I could see myself hanging with Gerald the most. His family reminded me a lot of my own family."

Fans can order prints of Durr's work online, and keep up with the artists' new projects on his Instagram.
