The Mysterious Mare Do Well

​ The Mysterious Mare Do Well is the eighth episode of the second season of My Little Pony Friendship is Magic, and the thirty-fourth episode overall.

Summary
The episode begins with Scootaloo heading the Rainbow Dash fan club in the Cutie Mark Crusaders's treehouse. She declares that Rainbow Dash should be declared the most awesome pony in Ponyville. Snails and Snips join in the discussion with their opinion of the best way to describe Rainbow Dash.

Rainbow Dash is then seen flying around and having a "dip in the clouds". Suddenly, she hears a filly shouting for help from a well. Rainbow Dash cuts short her cloud dip and saves the filly from the well, and is met with large amounts of praise from other ponies. She then sees a runaway baby carriage with a baby pony in it, and quickly saves the baby from plunging off a cliff. Again, she receives great amount of praise, and is then seen being photographed by paparazzi. She then gives a speech to the Rainbow Dash fan club in Sugarcube Corner. She brags about her new status as "hero" and the other main 5 are talking about her not being modest at all. Spike is in the corner writing her autobiography, when Twilight comes to tell Rainbow Dash that an autobiography is written by who it's about. Rainbow Dash scoffs and says that "I don't have time to write when I'm saving lives".

However, her pride soon begins to get in the way of her heroic deeds, and a mysterious mare in purple steps in. She begins to steal Rainbow Dash's thunder and becomes the new hero of Ponyville, dubbed "the Mysterious Mare Do Well" by the mayor of the town. Rainbow Dash attempts to outshine Mare Do Well, but she can't, and her hatred and jealousy towards Mare Do Well grows. Rainbow Dash keeps failing, and Mare Do Well keeps stepping in to fix her mistakes. It appears that Mare Do Well has wings, a horn, is super strong, super fast, and incredibly agile as well. Rainbow Dash realises that she cannot compete with that. Even her friends seem to be under the spell of Mare Do Well's awesomeness.

Rainbow decides that she has to convince the ponies in Ponyville that she is still heroic and awesome. However when she finds that there isn't anyone who needs saving, she ends up doing menial tasks like opening a jar of peanut butter and mowing a lawn in hope that people may praise her, but instead the townsponies roll their eyes and shrug her off as lame, leaving her even unhappier than before.

Rainbow goes off to brood on a thundercloud, wondering why people don't like her anymore and why she's all alone. When she hears her name called by Scootaloo, Rainbow assumes she's apologizing for forgetting about her, but Scootaloo tells her she's just inviting her to a thank you parade for Mare Do Well. At first Rainbow refuses, saying she wants to be alone. But then she hatches a plan to unmask Mare Do Well, and decides to go.

At the parade, when Mare Do Well appears, Rainbow comes up onto the stage and tries to get her to take off her mask. Mare Do Well runs away, but Rainbow gives chase. Mare Do Well keeps appearing in different places, too fast for Rainbow Dash. After a bit of chasing, Rainbow pins her down and pulls off her mask to see none other than Pinkie Pie. Astonished, she begins stammering. Then two more Mare Do Wells appear and pull off their masks, revealing themselves to be Twilight and Applejack. They explain that they wanted Dash to stop boasting so much and come off her high horse. Applejack stopped the runaway bus with her powerful legs, Pinkie used her Pinkie Sense to avoid the falling obstacles at the building site, Twilight used her magic to fix the dam, Fluttershy did the flyby at the dam, and Rarity designed the costumes. Rainbow Dash understands that she should act with grace and humility and not with selfish arrogance so as to avoid losing the appreciation of the townsponies as well as causing a rift of jealousy between herself and her friends. The episode ends with her holding a quill to write a letter to Princess Celestia and breaking the 4th wall by winking at the camera.
