This story is a sequel to Celestabellebethabelle
After the unfortunately unproductive visit of one Celestabellethabelle, cosmic forces being what they are have decided to deposit another unwelcome visitor in Equestria. Now it's Twilight and friends that are sent out to meet them. Those poor fools.
One for Star Vs The Forces Of Evil fans, or lovers of insane crossovers. A big thanks to Anonpencil, who was kind enough to give me permission to write a sort-of sequel to his masterpiece. 
Chapters (1)
Hooray! And it's out so soon!

Yup. I'm nothing if not punctual.
Star would LOVE Equestria. Adorable ponies and monsters to fight? Totally her bag.

And rarity would go full shipping mode trying to pair her and Marco together.
Now I'm wondering if there's going to be another entry in the 'weird pony visitor from another dimension' series.
Well that happened. I liked Pony head better when she was stuck in that school. Though with her penchant for parties you'd think she would have gotten along with Pinkie. Well done Darling
Ah, amazing!
8541909 Yes, but I kinda figured Pony Head would be the more interesting character to follow
8541923 Drama is kind of the story of my life, so I can kind of relate O Pony Head.
8542283 Who will they do next, though? Rainbow Brite's steed? Or one from the previous MLP generations? Wow... so many story possibilities, so little time.
8542432 I'm sure they would've got on like a house on fire... but even Pinkie has her limits. Badmouthing Gummy is one of them. I'd feel the same way if someone said horrible things about my cat, so yeah Ms Pinkemena, I'm with you all the way here.

I was thinking Lady Rainicorn from Adventure Time.

Ah, yes. I used to be into that, but it got a bit long-winded for me so I moved on. I can't believe it's still going... though, it ends next year, am I right? Maybe I'll catch up with it again... someday.
The title had me thinking you went and loosed Elmira Duff on the ponies. However clicking to get the full description and image showed you had mercy upon them. I don't know anything about Star vs the forces of evil but still I doubt that Mr. Pony Head is as much a plague upon the world as Elmira is.

I don't think that story would be very popular... I also don't believe there's a section labeled 'Cruel And Unusual Punishments'...

SVTFOE... good show, sucky ending.
If nothing else, this was amazing. :D
Though I will say you write an impressive Pony Head. XD

Thanks! Hope you try some of my other stories. I've written quite a few...
Eh.
Did Luna clone herself?
This was a joy to read. Good job!
