The upcoming crossover of Supernatural and Scooby-Doo has been in the works for over a year, but we're finally about to see the Winchesters go on a monster hunt with Scooby and the gang this week!

In this behind the scenes look at creating the episode, you can watch Jensen Ackles, Jared Padalecki and Misha Collins recording the audio for this hilarious new crossover. What you might not know, however, was said audio was actually recorded way back in April of 2017 according to the cast. That just shows how much time and effort it takes to create a bonkers episode like this.

The sneak peek also gives you an idea of the terrible conundrum the Winchesters find themselves in once they're in the cartoon — besides being in a freaking cartoon that is. The Scooby Gang has no idea that monsters are actually real instead of shady real-estate developers in masks, and Dean and Sam are determined to keep it that way. Unfortunately, they've found themselves in the one episode where their ghost seems to actually be a ghost. Jinkies!.

Scoobynatural airs this Thursday, March 29 at 8/7c on The CW.
