Scootaloo overhears Twilight talking about a time travel machine. She breaks into the library and travels back in time to meet her hero, Rainbow Dash, as a filly. It would have been the perfect plan if Dash had been anything like she expected.
The pets and their owners have swapped roles, making them ponies and their masters pets. Now the Sidekicks must travel across Equestria, go on the adventure of a lifetime, and discover their inner hero. Are they up to the task?

Scootaloo had been without a family for a very long time. She has never told anypony about her situation. It isn't until a certain purple unicorn learns about her origins that she discovers what a family truly is.
