I loved the episodes on this DVD. I thought the Princess Ponies learned their lesson about being selfish with their argument on who should be queen when they decided to take turns in the end. A noticeable goof in Part 4 was when Wind Whistler called Locket Wind Whistler and Locket called Wind Whistler Locket, probably because they were both in the wrong place (i.e., when something fell on Wind Whistler, it was supposed to fall on Locket because Wind Whistler wouldn't question what already happened).
The Golden Horseshoes looked a tad bit odd when Mimic wasn't feeling well. Otherwise, that story was excellent with its happy ending.
