[2][3][4][5] After solving a mystery that involves Dr. Najib posing as a mummy, Scooby-Doo, Shaggy, Fred, Daphne, and Velma feel like taking a break and having some fun.

Right after that, a greedy businessman - Dwight Monkfish arrives at the inn with the sheriff, the deputy and his assistant - Mitzi Capaletto.

Back at the Octo Rock Lounge, Velma accidentally invents a new dance move called the 'Jinky'.

Daphne goes to the Octo Rock Lounge to find Fred and Velma, but sees that everyone there is dancing, including the two.

Shaggy and Scooby arrive at the Octo Rock Lounge to tell her that they encountered the pirates, but they show up and terrorize the teenagers.

Rob and Laura and walk the gang towards their rooms, where Scooby accidentally discovers the old secret tunnels that the smugglers used.

They are forced to walk the plank, but Tommy and Brenda arrive in a speedboat, which helps the gang escape.

The ghost pirates are then revealed to be Chad and Krissy, and Velma explains that they just couldn't let go of their titles as captains of the bash and tried to shut down the celebration to avoid giving it up.

Rob and Laura confessed their crimes, and said that they only wanted to find the missing treasure and needed to hold on to the hats so they could keep looking.

Daphne also reveals that the sheriff and the deputy sabotaged the coaster to stop tourism so they didn't have to work so hard.

Velma successfully solved the poem of the missing treasure and they use it to rebuild the boardwalk with Monkfish having a change of heart and returning the property.

Renee Longstreet for Common Sense Media gave the film a two out of five star rating and commented, "No surprises in this routine adventure for the gang; they behave in expected ways, solve an expected mystery, and manage a few funny jokes and sight gags about their short, blocky limitations.

Ghosts and pirates made of synthetic material simply can't be scary apparitions or swash and buckle like they can when animators are given a free hand.
