The series, while still following the basic mystery-solving format of its predecessors, was broadcast as a 52-chapter animated televised novel and included elements similar to live-action mystery/adventure shows such as "Buffy the Vampire Slayer" and "Lost." An overarching mystery surrounding the gang's hometown of Crystal Cove, California became the series' main story arc, with pieces to the mystery unfolding episode by episode. Also featured were romantic entanglements and interpersonal conflict between the lead characters. The series ran for 52 episodes over two seasons, with a three-part finale airing across April 4 and 5, 2013—exactly three years from the debut.
