Supernatural fans are only a little over a month away from the highly anticipated Scooby-Doo crossover episode, but a few lucky fans will actually get to see it sooner than the rest.

When Supernatural hits PaleyFest on March 20, it’s bringing a special treat. Translation? Supernatural‘s PaleyFest event will serve as the world premiere for the Supernatural–Scooby-Doo crossover, which is appropriately titled “Scoobynatural.”

The crossover — which will air on Thursday, March 29 on The CW for the rest of the world — was first announced at the CW Upfronts in May 2017. And for the most part, details of the episode have been kept under wraps. At this point, all we really know is what co-showrunner Andrew Dabb previously told EW: “It’s more adult than your average episode of Scooby-Doo.”
