A group of ghostly skeletons under the command of a bratty 10-year-old pirate named Youngblood attacks FentonWorks and steals the ghost shield. Soon after, all the adults in Amity Park are packing for a cruise without their kids. Danny, Sam, and Tucker discover that the cruise is a hoax and the adults are under the spell of a mysterious (and cheesy) song created by Ember to make them into galley slaves for Youngblood's pirate ship! The stolen ghost shield prevents Danny Phantom from getting on board the ship, so Danny Fenton has to lead Amity Park's teenagers in a daring attempt to save their parents.
