On Supernatural Season 13 Episode 16, Sam, and Dean are in the middle of fighting a giant plush dinosaur in a pawn shop, but are able to get the upper hand. When the plush toy is destroyed, the owner of the shop offers to give them anything they want in the shop for saving his life. Dean decides to choose a TV, and the guys head back to the bunker.
Dean installs the TV, but when he shows it off to Sam, they are instantly transported into an episode of Scooby-Doo. Dean is excited, but Sam is cautious about the entire thing as this isn't something which normally happens. Dean tells Sam to just go along with it, and soon enough they join the Scooby gang on a mystery.
Unforunately, things quickly take a turn for the worse when the ghost what was in the haunted house turns out to be a real ghost, and it's really killing the characters on the show. The guys are soon greeted by Castiel who also got sucked into the TV when he stopped by the bunker to check on the guys.
Castiel, Sam, Dean, and the rest of the Scooby gang decide to figure out what is going on. They devise a play to capture the ghost in a circle of salt. They're able to catch the ghost quickly, and it turns out it's a young boy who was being used by a man named Jay who owns the property the pawn shop is on. Jay had been using the child to scare off people so he could get a better deal on the property.
Sam, and Dean are able to free the young boy after he transports them back to the real world. They later get revenge on Jay after doing some research, and finding out he had been evading taxes. The cops show up, and arrest him.
