Assigned to stop a group of poachers who broke out of prison from killing off an entire city of seaponies, Twilight must turn the Mane 6 into seaponies to save the helpless creatures. On the way they a find Pinkie Pie's long lost seapony brother and a unicorn who disappeared many years ago.

Rating may change from Everyone to Teen, depending on how violent i want to make this :scootangel:

(Ps. In this story, Seaponies are basically Merponies, having fish tails, but I prefer the term 'Seaponies', so that's what I did. Deal with it.)
