Twilight Sparkle's friends couldn't have picked a worse time to be away if they tried! The Crystal Heart has gone missing, and with the rest of the mane six in Griffonstone, it's up to Princesses Twilight, Cadance, Luna and Celestia to find it!

Though despite the almost apocalyptic level of danger, the other princesses don't seem to be taking the mission seriously. Is something wrong with them? Have they been mind controlled? Is Twilight about to crash into a tree if she doesn't stop thinking about this and start looking where she's going?
