There were three waitresses at a restaurant in Ponyville known as "The Oat & Apple". Their names were Pinkie Pie, Rainbow Dash, and Applejack. However, they find a golden device that sends them to a weird universe full of pony pirates and ships one day after work. Princess Twilight Sparkle needs help rescuing her older brother, Shining Armor, from her father's rival; Captain Fancy Pants. He wants to kidnap Twilight and her brother, so he can have the throne rather than their father, which is his brother, King Blueblood. Her royal adviser, Rarity, highly discourages her, but Twilight does what she thinks is right anyway. The three unlikely mares find themselves in assisting in the rescue plot. Can they save Prince Shining Armor before he gets killed by Captain Fancy Pants?
