Could I trouble you to ask as to what the storyline was? And what they sounded like, the music etc??? That would be so wonderful if you could!
No trouble at all, it would be my pleasure!
The sneak peek only had a narrator and some music (but not songs). That means we're not gonna find out through that trailer what a speaking Tinker Bell sounds-and looks- like. The music is only instrumental- nothing special, it sounds just like any other music score for a movie trailer.
As for the storyline, the narrator says: "Welcome to Pixie Hollow
, a place no mortal has ever entered... until now!"
Then, she continues with an introduction of some of Tinker Bell's fairy friends such as "Iridessa, sparkling light fairy, Rosetta, the beautiful garden fairy" and some more. She also informs us that Fairies have a queen, Clarion. Each fairy's mission is "to become wing maiden and spread imagination to the children of the world, using pixie dust". The narrator goes on to let us know that "something is dreadfully wrong; something that threatens the very existence of Pixie Hollow. Now, only Tinker Bell can save the world of fantasy. She must find the true magic of pixie dust!" and then she says that pixie dust is very real...if you believe.
As a conclusion, the narrator says: "Help Tinker Bell unlock the secrets of Pixie Hollow!".
