Spike, Pinkie, and Rarity go to the kingdom of diamond dogs, which unlike the ones they met a few years ago are actually pretty friendly. The problem seems to come from the royal family's daughters, Fiona and Amber. Fiona seemed to be a bit spoiled and doesn't think about others that she deems below her. Amber on the other hand is a tomboy who feels confided. Rarity and Pinkie both help each sister in their own ways.
