Celestia, princess of the sun, and mare of the morning is in dire trouble. Her long running prank war with Luna had resumed ever since she had returned from the moon, and since then, she's been on a loosing streak! And of course Luna is always there to rub it in her face every step of the way. But while she was looking through some of Twilight's old letters on friendship lessons she's learned, Celestia has a sudden surge of inspiration on how to prank Luna back. And she'll need Zecora's help to do it.
And if her plan goes well, it means Luna will get knocked down a few pegs, or several in this case. And then, she'll have to contend with her extremely big sister!
