Netflix announced the series in a statement released on Monday 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 Duffer brothers, creators of the original Stranger Things series, said in the statement.

Netflix had previously announced that a Stranger Things spinoff show was in the works and a play that will debut at London's West End in November.
