Just in time for the 13th season of the show to be released on DVD next Tuesday, Supernatural showrunners Robert Singer and Andrew Dabb have revealed that there was an approximately 1-minute scene which had to be cut from the final version of "Scoobynatural" due to time constraints. The scene features Shaggy, Scooby dressing up with Castiel as waiters to fool the green ghost. You can watch the exclusive deleted scene here courtesy of EW.
Though it appears for the time being that there will be no DVD release which includes the "Scoobynatural" episode only, you can purchase the full thirteenth season DVD in stores on Tuesday, September 4. The DVD will also include the exclusive deleted scene which was not featured in the original run of the episode.
