The third episode of Season 3 has been tossed up on Zap2it. They have accidently absorbed the wrong episode before, but I think this one sounds pretty normal compared to Strawberry Elves.
Confirmed!
Head on down past the break for synopsis and title!
Title: Too Many Pinkie Pies
Synopsis: Overwhelmed with having to choose just one friend to spend time with, Pinkie Pie uses a magic mirror to clone herself.
Air Date: November 17, 2012
So many Pinkie Pie's!
And a side note, it looks like the s3 intro will be a two parter on the same day if this air date is correct.
Thanks to Boogster Su for the heads up!
