Rainbow Dash and Scootaloo weren't born sisters, they became sisters by choice. In an attempt to help Apple Bloom, Scootaloo accidentally puts the bond of that sisterhood to the test.

Now the two pegasi will learn just how far they are willing to go for each other, and just how strong their bond as sisters of loyalty really is.

To Scootaloo crusading for her cutie mark had always been more of an excuse to get her friends to join her in her idea of fun. But now that they have earned their cutie marks and moved on with their lives, Scootaloo is determined that today she will earn her own, and catch up to her friends.

When a friend falls ill with a rare disease, there's only one pegasus in all of Equestria that can hope to retrieve the cure in time.

The cutie mark crusaders find a magic artifact that makes them live a day in each of their other friends bodies.

The crusaders then decide to have fun pretending to be each other, after all how much trouble can three best friends get into pretending to be each other?

Only problem is Scootaloo has secrets. Secrets she dares not share even with her best friends.

Tagging note: I don't consider this a pure adventure story as there are two distinct chains of events unfolding in this story. one is an adventure story the other is better described as a slice of life story. So fair warning, don't be surprised by the rather long interruptions to the adventure story stuff.

In many pegasus museums there is a mural depicting a time long ago, when the pegasus tribe stood alone, four pegasi charging into enemy archery fire. This is the story behind that mural. The story of the war of the pegasus tribe.

Pergasi are creatures of the sky. But what happens when one flies as high as they can only to find themselves still longing to fly higher? With a little help from the most unlikely of sources one young pegasus will find out.

There's a new pony in town and while he seems content to keep to himself Sweetie Belle takes it on herself to get him to open up.

Through trial, error and perseverance Scootaloo endeavors to learn how to fly with help from Rainbow Dash.
