LITTLE TWYLAby, Doll or Playset?

Last monday, May 20, 2013, Mattel filed for Little Twylaby with the description of Toys, Games and Playthings. 

Could it be a playset for Twyla?

Others guessed that it might be a little Twyla, or Twyla's sister but I doubt it because it was not filled with doll, accessories and clothing.

What could it be? What do you think?
