"Raving reople, runting rings -- the ramily rusiness, Raggy."

While Sam and Dean Winchester have 13 seasons of monster hunting under their belt, there's no doubt that they'll be learning a thing or two from the Mystery Inc. gang.

In honor of the upcoming Supernatural/Scooby-Doo crossover event -- "Scoobynatural" -- Hot Topic will be releasing merchandise featuring the Winchester Brothers and Mystery Inc.

So far, they retail giant have given us a peek at four different t-shirts, as well as a pin, patch, and sticker. All designs include Sam, Dean, and Scooby, but others also have Castiel, Velma, Shaggy, Daphne, and Fred.

There's even one groovy t-shirt design with the Mystery Machine's signature flowers, adored with some colorful pentagrams. You can also pick up a purple tie-dye tee, also with pentagrams and the cartoon characters,  if that's more your style. The matchups may seem odd at first blush, but it's definitely the kind of aesthetic we can expect from the crossover event in general.

The line of merchandise will be available from Hot Topic in-stores and online on March 20.

Starring Jensen Ackles as Dean Winchester, Jared Padalecki as Sam Winchester and Misha Collins as Castiel, Supernatural‘s 13th season resumes with “ScoobyNatural,” Thursday, March 29 at 8pm on the CW.
