Pups and the Ghost Pirate

It's Halloween-time in Adventure Bay, and the pups are trick-or-treating. However, trick-or-treating is cut short when Cap'n Turbot's "pirate" ship, where a Halloween Party is being held, mysteriously drifts off along with a boat-load of passengers and a series of unexplained ghostly business. Ryder and the pups must board the ship and try to make sense of all the unexplained ghostly actions.
