I sent Hot Topic and message about my Cartoon Hangover plushies I made and asked if they're going to make Alicorn Twilight, Rarity or Applejack vinyl figures soon. This is what they said to me.
"Aww thank you! Yes - we do have plans to complete the Mane 6! Unfortunately none of those 3 will be in our next series, but I think you'll like the ones we chose! We actually will have a Catbug plush hitting stores around holiday time, and we have our eye on Puppycat as well! Unfortunately we do have to go through our official licensees for these items. Your plushies are so cute! You definitely have talent -HT Nerdette"
