History[]
The 13 Ghosts of Scooby-Doo[]
When Daphne Blake, Scooby-Doo, Shaggy Rogers, Flim-Flam, and Scrappy-Doo came into his travel agency looking for a vacation in order to calm Scooby's nerves (Scooby had become frightened from the constant ghost hunting), he, disguised as a travel agent, suggested an ocean cruise on the Queen Mertyl. He handed Daphne the tickets to the cruise, and the gang left the agency.

Captain Ferguson as a human
Later, on the cruise ship, he revealed to be both Captain Ferguson and the travel agent, as well as the ghost of the captain who sunk with the ship fifty years earlier. He chased the gang around the ship, but was eventually swallowed by the tornado-like body of a cyclops demon who escaped from the Chest of Demons, after the ship crossed into the Bermuda Triangle.
