Three times during the Diamond Dog Caves Area, there will be a locked door guarded by one of the Diamond Dog Trio: Spot, Fido, and Rover. Each time you meet one of them, they'll explain that they aren't here to fight, due to orders from their new "High Princess"
. They'll explain their orders to test you with a quiz, and begin asking you questions. Questions could include, "Who was the first one to show their Element in the Everfree Forest on the night of Nightmare Moon's return?" "What did Spike give to Rarity?" "What is Cadance's full name?" "Name the colors of Celestia's mane?" "Who was the ancient leader of the Earth Ponies?" and so on and so on. The first door is easy. The second door is medium. The third door is hard. If you answer all three quizzes and get through all three doors, then you'll complete the area and move on to meet this "High Princess" of the Diamond Dogs. I wonder who it could be?
