What is the name of the 1985 Scooby-Doo series featuring Vincent Van Ghoul?

The 1985 Scooby-Doo series featuring Vincent Van Ghoul was The 13 Ghosts of Scooby-Doo.

The show followed Scooby-Doo, Shaggy, and Scrappy-Doo as they tried to recapture thirteen ghosts that Shaggy and Scooby had accidentally released from a chest. Vincent Van Ghoul, voiced by Vincent Price, assisted them as a supernatural expert.

Unlike many earlier Scooby-Doo stories, the ghosts in this series were genuinely supernatural rather than criminals in costumes. The group also included the young con artist Flim-Flam, who joined the chase and became a notable franchise character.

The title refers to the central group of ghosts, not to thirteen episodes. The series ran for thirteen episodes in 1985, which is one reason the number is sometimes mistakenly associated with its episode count.
