Supernatural’s ScoobyNatural Extended Trailer Released!

One week before the crossover premieres, The CW has released a new extended trailer for Supernatural‘s live-action turned animated episode, “ScoobyNatural.” Watch it now in the player below, and check out the episode images in the gallery!

“Sam (Jared Padalecki), Dean (Jensen Ackles), and Castiel (Misha Collins) are transported into the animated world of Scooby Doo where they join forces with the Scooby gang to solve a ghostly mystery. Robert Singer directed the episode written by Jim Krieg & Jeremy Adams.”

Adams — who originally pitched the idea — and Krieg are screenwriters known for their work on a variety of action-adventure projects, including LEGO Scooby-Doo, Justice League Action, and LEGO DC Comics Super Heroes: The Flash. Krieg, in particular, has a long history working in the Scooby-Doo realm. The pair teamed up with the Supernatural cast and crew alongside animation director Spike Brandt and Warner Bros. Animation to make this crossover a reality.

It sounds like the mystery will actually start with a free TV that is offered up to the brothers by a grateful pawnshop owner after Sam and Dean work a case-of-the-week. In the trailer, the Winchesters are zapped into the Scooby-Doo world through that same TV. Dabb and co-showrunner Robert Singer teased that the crossover “gets pretty dark,” and that “there are things you wouldn’t see in a regular Scooby-Doo cartoon.” Dabb explains that the boys “walk into an old episode of Scooby-Doo,” but it “may end up being a new episode of Supernatural,” so don’t expect the monster to be a man in a mask.

Supernatural’s “ScoobyNatural” episode will air on March 29 at 8 p.m. ET on The CW.
