On the outside, the entrance to the bunker is set into a hillside beneath an abandoned power plant. Immediately inside is a command center with 1950s technology and a library with a great deal of lore on the monsters of the Sam and Dean's world. Deeper in are several bedrooms, one of which Dean converts into a "man cave" with his new TV. The bunker is known to contain an archive room and its own dungeon as well. The bunker contains a garage with several vintage cars left over from the 1950s, Baby and a motorcycle belonging to Dorothy from the Wizard of Oz parked within.
After returning to the bunker from their latest case, Dean set up a "man cave" with his new TV. As Dean played with the TV, he and Sam were unexpectedly pulled into the episode A Night of Fright is No Delight of Scooby-Doo, Where Are You! along with their car, possibly because Dean had the keys in his pocket. When Castiel returned to the bunker, he briefly saw Dean and Fred Jones racing on the TV before he too was sucked into Scooby-Doo.
After solving the case, the Winchesters and Castiel were returned to the bunker by the ghost kid. Dean retrieves a sledgehammer and a blowtorch from another room and uses the sledgehammer to smash his new TV, allowing Dean to recover the pocketknife the ghost is attached to. After promising the ghost that they will deal with Jay, Sam melts the knife with the blowtorch, causing the ghost to turn into a ball of energy that rises upwards towards Heaven.

- The bunker was once the base of operations for a secret society known as the Men of Letters. The organization was wiped out in 1958 by the demon Abaddon.
- In Supernatural, the Men of Letters bunker acts as the Winchesters home and main base operations starting in the middle of the eighth season. It is described as "the safest place on Earth, warded against any evil ever created" and is stated to contain "every object, scroll, spell ever collected for thousands of years under one roof. It is the supernatural mother lode."
- It is usually just called The Bunker on Supernatural.
- The ghost kid is not the first ghost to haunt the bunker. In the Supernatural episode Captives, taking place about four years before Scoobynatural, the bunker was haunted by the ghost of Kevin Tran, a young man who resided there briefly and was murdered within. At the end of the episode, his ghost left with his mother.
