Scoobydoo First Frights Rom Direct

I need to mention the horror elements, which are more intense in this film compared to the usual light-hearted mysteries. There might be jump scares, darker themes, but still appropriate for the target audience. The user might be interested in how this movie stands out from others. Also, include some fun facts, like it being a direct-to-video release or part of the Shaggy Rogers series. Maybe the film was part of a wave of more horror-focused Scooby-Doo movies around that time.
