Development
The director, Mike Milo, believed it would be easier to get Axl Rose since he had already played an animated version of himself in the New Looney Tunes episode "Armaggeddon Outta Here, Part 2." The plot of the episode came from Rose's interest in archaeology and motorcycles.

Filming
Rose prefers to work late, wanting to get in at 11 PM, but Bailey, concerned about his staff being too tired, countered with a compromise of 9 PM.

It was copyrighted in 2020.

Music
The theme song, entitled "Scooby-Doo, Where Are You?," was written by Chris Bailey, and performed by David Poe. It was produced by Vivek Maddala. The episode's main music was performed by Peter Bateman and Sunna Wehrmeijer.
