In the darkness, some pony farted.

An army of Ursa Minors, led by the evil Ursa Major, bears down upon the united ponies of Equestria. Alone, these brave soldiers are helpless against the army of monstrous creatures, but with the help of Earth's greatest champion, they may just stand a chance of prevailing in the upcoming battle.
