Fans of The CW’s Supernatural will want to “toon in” to tonight’s episode as Dean, Sam, and Castiel are transported into the animated world of Scooby-Doo where they join forces with the Scooby gang to solve a ghostly mystery. “The bulk of the credit for this episode goes to Warner Bros. Animation. Everything we gave them, they elevated,” co-showrunner Andrew Dabb told Entertainment Weekly. “There were no disappointments for me here. This is one of the few episodes of Supernatural I can watch and just be a fan of because it feels like someone else took the material and made it into something really, really great. It was a weird absurd swing for us but I think it worked and people are going to really like it.”

“It feels like a really good episode of Supernatural that the Scooby-Doo people happen to be in. It doesn’t feel like we’re mortgaging the show to make it fit into the Scooby-Doo world. It really clicked together in a way that we think is very special.” Co-showrunner Robert Singer adds, “It was terrific right from the beginning. That said, having seen the animation, it’s actually better than I would’ve hoped. We had a really good time recording the voices last spring and the guys were just so into it and in a way, we’re changing their performance of what their characters were to fit the cartoon mold, but everybody embraced it right from the beginning and it came out really well.”

The episode, directed by Robert Singer, airs tonight on The CW and will be available the next day for free on The CW App: http://go.cwtv.com/genSPNyt
