The latest in Disney’s animated Tinkerbell series adds Ginnifer Goodwin to the cast. Coming in March of 2015, it explores the ancient myth of a mysterious creature whose distant roar sparks the curiosity of Tinker Bell’s friend Fawn, an animal fairy who’s not afraid to break the rules to rescue the NeverBeast before time runs out. The fairies meet Gruff who is a massive creature and the subject of an ancient Pixie Hollow myth. Hidden in a dark lair on the fringes of the fairies’ beloved home, Gruff is discovered by curious and empathetic animal fairy Fawn, who sees something special in his glowing green eyes. His penchant for stacking rocks mystifies Fawn and her friends—but Gruff’s true purpose is the real surprise.

It also features the voices of Mae Whitman (Tinker Bell), Megan Hilty (Rosetta), Lucy Liu (Silvermist), Raven Symone (Iridessa), Anjelica Huston (Queen Clarion) and is directed by Steve Loter (“Kim Possible”) and produced by Makul Wigert (“Secret of the Wings”).
