An animated series set in the sci-fi world of ‘Stranger Things’ is in development at Netflix, part of the streaming service’s efforts to expand the hit series into a wide-ranging franchise.

Netflix announced the series in a statement but gave no title or release date and few details.

“We’ve always dreamed of an animated ‘Stranger Things‘ in the vein of the Saturday morning cartoons that we grew up loving,” the original Stranger Things series creators, the Duffer brothers, said in a statement.

Stranger Things premiered on Netflix in 2016 and quickly became the company’s most popular English-language show.

The show follows a group of teens as they deal with strange occurrences in the fictional town of Hawkins, Indiana.

Netflix previously announced plans for a Stranger Things spinoff show as well as a play that would premiere in London’s West End in November.
