Corrected entry: As the witches' spell begins the Ponies pause and look around. Sundance (white Pony with pink hair) is standing with the group, yet she does not feature at all in this set of episodes.

Correction: There are lots of movies that show characters that are not primary to the plot line, much like an extra.
