"Supernatural" remains one of the most enduring shows on television. Now and then, however, something needs to be done to spice things up and keep the show material fresh. To that end, the show is going to go down a very different route for one episode next season - an animated route. The cast members won't be alone in the endeavor, however, as some rather famous friends will join them.

Scooby-Doo, where are you?

During the upfront announcements for The CW, actors Jensen Ackles and Jared Padalecki announced a crossover animated episode inspired by Scooby-Doo. The "Supernatural" stars also swore it was not a joke, so they'll be breaking a pretty big promise if it proves to be a ruse.

The special episode will air during the show's thirteenth season next year.

How will an episode with Scooby-Doo work for the show, one could ask? That's a fascinating question with no easy answer. Maybe Sam and Dean will run into some villain with a mask, the kind the folks in the Mystery Machine see every day. Or maybe they'll decide they want a pet and it ends up being Scooby, which forces the rest of the gang in their lives as well. There's no obvious intersection between "Supernatural" and one of the world's most famous animated cartoons. They'll try to make it work though because it's the thirteenth season - time to have some fun.

The CW loves crossover episodes

The CW has an extensive history in attempting various crossover episodes. There have been several crossover moments between "The Vampire Diaries" and "The Originals," which was spun out of the former back in 2013.

Additionally, the network attempted a multi-night crossover between almost all of their superhero properties this season, from "The Flash" and "Supergirl" to "DCs Legends of Tomorrow." That was met with mixed reviews.

The problem with a Crossover Episode is that it can be seen as a cheesy way to either fill time or fill audience metrics. The interest tends to be more in the combination of character than any actual character or plot development. To some, they could be considered "jumping the shark." That may not be an issue for "

That may not be an issue for "Supernatural," simply because it has been on for such a long time now. Instead, the showrunners feel they can do as they please on their neverending show. It's a risk, but it could be a fun risk if executed properly - it will be up to the show's loyal fans to have a final judgment on the topic. Stay tuned..
