A princess star fairy named Sparkle lives up in the clouds in Castle WishStar. Her job is to grant wishes to children when they wish upon a star. But lately, she has been overwhelmed by the increasing number of wishes being made. So she asks for help and receives not one but five new star fairy helpers. But more troubles arise when they meet a little girl who is upset but cannot think of a wish to make her happy.

When the wishing star disappears, Pinkie and all of her pony friends go on a journey to find it.

The Warner Brothers (and the Warner Sister) go on a quest to find a fallen wishing star to help Dot with her illness. Unfortunately the rest of the town, including an evil king, also hear about the star and want to get to it first to have their own wishes come true. It's a race against time and it's up to the three zany siblings to get there first.
