Phantom pirates

"It's vacation time for the ghosties, but instead of a luxury cruise, the crew of lovable specters has accidentally taken their holler-day on a ship full of phantom pirates! But that's not the worst of it--these naughty priates are planning to invade a ship of still-alives (and that's not a very polite thing to do at all). The ghosties decide to step in and help the still-alives, so it's up to Pamela Fraidy and her ghosty friends to save the day. But to turn back the pirates they're going to need help from a mischievous mermaid, some nose-plugs, and whole lot of garlic"--Jacket.
