When the Scooby gang visits a dude ranch, they discover that it and the nearby town have been haunted by a ghostly cowboy, Dapper Jack, who fires real fire from his fire irons. The mystery only deepens when it’s discovered that the ghost is also the long lost relative of Shaggy Rogers!
Unfortunately the movie Scooby-Doo! Shaggy's Showdown is not yet available on Disney Plus.
