The 13 Ghosts of Scooby-Doo
Daphne Blake, Scooby-Doo, Shaggy Rogers, Flim-Flam, and Scrappy-Doo visited the travel agency searching for a vacation in order to calm Scooby-Doo's nerves. The travel agent suggested an ocean cruise to Bermuda on the Queen Mertyl cruise ship.
Film-Flam then showed Scooby the fish tank to emphasize the ocean, but Scooby became frightened after he saw a poster of a dragon through the glass of the fish tank. He ran towards Shaggy and knocked him into a wall, causing the African mask hanging on it to fall onto Shaggy's head. Upon seeing the mask on Shaggy, Scooby quickly darted away from him. After Daphne explained to Scooby that he saw a mask and a travel poster, rather than two monsters, the travel agent handed her the tickets, and the gang exited the travel agency.
