Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) are about to embark on their most bizarre mission yet.

In the official teaser for Supernatural's crossover episode with Scooby-Doo, the boys find themselves sucked into the famed pooch's animated world where hijinks are sure to ensue.

"Once they get over their amazement at being in the cartoon, two things happen," executive producer Robert Singer told Entertainment Weekly. "They say, 'We've been in a situation like this before with the Trickster and I think we're supposed to play this out.' And then they realize they're in a Scooby-Doo cartoon, which makes Dean incredibly excited because Scooby-Doo was his favorite cartoon growing up."

Aside from fanboying over the iconic gang, it looks like Dean will make the best of the situation in the most Dean way possible by hitting on the nearest woman. "Dibs on Daphne," he tells Sam in the preview.

Watch it all go down when Supernatural's Scooby-Doo crossover airs Thursday, March 29 at 8/7c on The CW.
