Premise:
Despite Twilight using her spell, Fluttershy still finds herself transforming at night. But instead for apple juices, this time she hundreds for blood. Each night she infiltrates one of her friends homes and drinks their blood, infecting them and turning them into a Bat Ponies just like her...

One night Spike wakes up and spots Twilight sneaking out and heading towards Sweet Apple Acres. He follows her and catches her meeting up with the rest of their friends, excluding Applejack. She does arrive though, the rest of the group (having lured her there) almost immediately gang up on her and bite her turning her into one of them!

Spike freaks out and flees towards the farm, at the same time Applebloom get's worried due to Applejack being out so late and sneaks out of bed. She runs into Spike who reveals whet happened right before the now-turned 'Applebat'(Spike starts giving their vampire sides nicknames) appears, the rest of her friends having gone to turn the rest of Ponyville.

She attempts to bite Applebloom but Spike gets in the way, however he isn't turned due to the fact that he's a dragon and his scales are tougher then rock (not hard to believe considering dragons bathe in lava). The two flee with Applebat hot on their tails and just barley manege to lose her in the forest.

They quickly make their way to Ponyville and end up running into Scootaloo, who reveals that 'Count Dashula' had already turned her parents while she barley escaped. The trio then heads toward Rarity's Boutique just in time to save Sweetie Belle from 'Rariteeth'. Rariteeth try's to seduce Spike in order to bite him but get's the same results as Applebat. Spike and the CMC just barely manage to escape.

Now the four of them must evade the turned mane six and warn all of Ponyville before they are all turned into Bat Ponies!
