Twilight, in an effort to help Applejack and Rainbow Dash achieve their dream of having a foal together, casts a spell that, unbeknownst to the princess, envelops all of Ponyville and plunges the little ponies (and one dragon) into a vortex of unknown genetic exchange and unplanned parenthood. What's more, the solution may come with severe complications of its own, and thus Twilight finds herself tasked with finding a resolution where there is likely none to be had.
