Princess vs. Pirate Ghost

Princess vs. Pirate Ghost is a Halloween special video based on one of Sarah West's requests for WRJ WRJ.

Plot
The day before Halloween, Princess Anna from Frozen and her friends discover that a pirate ship has mysteriously appeared on the docks of Arendelle's fjord. The ship looks like it's in terrible shape, but there are no sailors on the ship. They are all puzzled at the sight of it, and wonder how the ship got there if there aren't any sailors on it and it doesn't look like it's in perfect sailing shape. Anna is still very curious about the ship, and decides to take a better look at it. As she steps inside, she finds something amazing. It's a treasure chest, filled with gold coins and shiny jewels. However, there's a label on the chest that says "Do not open". Anna feels tempted to open the chest,

After Anna regains consciousness, she realizes that she is now somewhere different. To her shock and horror, the Flying Dutchman from SpongeBob Squarepants appears

He tries to scare Anna by shapeshifting into numerous horrific forms and warping reality effortlessly, but it doesn't work, because Anna doesn't get frightened that easily. Then he tries to hypnotize her by creating visual illusions of humanoid men dancing and chanting "the power within" over and over, but that doesn't work, either.

Anna is not going to take being held hostage by an evil ghost pirate for long. Once the Flying Dutchman's back is turned she runs and hides in a corner, and when the time is right, she decides to call for backup

This scares the Flying Dutchman and he flees in terror.
