Once again, Rainbow Dash finds herself called upon but the Cutie Map to solve a friendship problem, this time in the desert just outside the town of Somnambula. However, for reasons Rainbow Dash can’t possibly fathom the Cutie Map also sends a pony who’s only now started to learn about friendship himself, namely Moonwhisper, Twilight’s bodyguard/special somepony. Is Moonwhisper ready to solve the friendship problem of somepony else? And what sort of friendship problem could possibly require the combined talents of Rainbow Dash and Moonwhisper to solve?
