Playing pirates at the Ponyville Tavern
One fine day, Princess Yuna and her friends were told a great story by Mr. Pym about a long lost treasure through the Equestrian Caribbean. Yuna enjoyed it very much as she and her friends help out with Sir Ector and Sir Kay at the tavern. The foals started pretending to be pirates. Every time Sir Ector overhears, Pound Cake and Pumpkin Cake began to wonder how'd he does that. Yuna was pretending to be the captain with Twila pretending to be first mate.
Mr. Spivey alerts the foals with the Bone Pirates' Black Spot
Then, There was a huge knock on the door, It was Captain Stubbs' spy, Mr. Spivey. He warned the foals and showed them the black spot. Yuna was horrified about the attacking pirates of evil. So, They've started packing their things from the tavern and Mr. Spivey showed them a treasure map. The map of the treasure of the Equestrian Caribbean. So, the foals became pirates of Equestria. Suddenly, Someone made a loud knock on the door. It was Captain Bonemeal and his gang of bone pirates, Ribbs, Kolestra and Spiny as they bust through the tavern. The foals fight off the pirates as Yuna went up stairs and warn Sir Ector and Sir Kay. They send her to the back stairs as they hold them off. Yuna ran to get her friends and cousins before the explosion at the tavern was made. So, They hurried straight to Skylands.
