This pattern is different than the other Frog Princess doll pattern by JanaGeek. This pattern is only available in a kit, not online. It has a bigger head and a smaller body than the JanaGeek pattern.

As a helpful reference, here is a list of the yarns I used to make the doll pictured in the “Disney Princess Crochet” pattern book.
