After almost thirteen years on the road, The Winchester brothers have faced all manner of demons, monsters and have even dabbled with time-travel. However, an episode of the forthcoming thirteenth season will see Sam & Dean join a legendary canine crime solver in the animated realm. That's right; The Winchesters will team up with Scooby-Doo in a fully animated episode extravaganza. Zoinks!

The announcement was made at The CW's upfronts presentation in New York by Supernatural stars Jensen Ackles Jared Padalecki. There's no word yet if Shaggy, Fred, Daphne, and Velma will be appearing, I just hope they leave Scrappy-Doo out of it.

On paper, that might sound like an impossible fusion of TV shows that can't possibly work, but Supernatural is no stranger to breaking the fourth wall. In the season six episode The French Mistake, The Winchesters are thrust into an alternative reality where they are actors on a TV show called Supernatural. They've also attended a high-school musical based on their exploits, and who can forget that God wrote all those Supernatural fan-fiction books. So when you think about it, making an entire episode in the retro Hanna-Barbera fashion featuring Scooby-Doo, isn't really that out there for Supernatural.

The Winchester Brothers have been immortalised in animated before for the short lived anime series back in 2011. Meanwhile, the live-action series is officially the longest-running TV show on The CW, but the end of the road could be on the horizon. Late last year, Jared Padalecki revealed that he and Jensen Ackles were hoping to make it to the 300 episode mark before bowing out.

"If we don't make it to 300, I think Ackles and I will both be truly bummed. When we get to 300, I think Ackles and I will think it might be time to say bye. There's a chance that changes, but we certainly do not take it for granted that we're going to make it to 300."

The future of Supernatural beyond season thirteen might be unclear, there's still plenty more to come, and this Scooby-Doo crossover sounds inspired. The as yet untitled episode is expected to air in the first half of the forthcoming season that kicks off in October.
