Tread Perilously's crossover month continues as Baby and the Mystery Machine collide in the Supernatural episode called "ScoobyNatural."

When Dean is awarded a widescreen TV for defeating a haunted dinosaur toy, he and Sam are transported into the animated reality of Scooby Doo, Where Are You! -- episode 16, "A Night of Fright Is No Delight" to be exact. While Sam frets about being a drawn character, Dean turns into a total fan even as he attempts to tempt Daphne away from Fred. But the merriment may get cancelled when the lighthearted events of the plot turn to real murder. Will a haunted television turn this crossover into something lethal?

Justin admits to never being a Muppets guy, but he shares Dean's affection for Scooby Doo. A discussion of children's cartoons and the Looney Tunes breaks out. Erik envisions voice actor Frank Welker's mobile recording studio. Justin argues for Velma Dinkley as a Bisexual Icon. Justin waxes about the musical chases in the original series. The Scooby Doo and Supernatural formats are examined. The tendency toward real estate developers as the villain is explained. Matthew Lillard once gets all the praise, as does Grey Griffin. Velma and Sam prove to be a fruitful pairing and Erik tries to figure out why the episode's animation leaves him cold.
