After a new student comes to Ponyville, strange things begin to happen. It seems as if every pony in Equestria is dying because of...well..drinking water! What if there IS something there in the water...?
Every pony's hearts seem to explode after making contact with any of Equestria's water source. It's up to the mane six to figure out what's wrong with Equestria before they are the only ones left with a heart and soul.
