The Heart of Te Fiti is a small oval-shaped light green stone with a swirl engraved in it.
Behavior During Gameplay
The figure's behavior during gameplay is unknown.
How to Unlock
The figure's unlock requirements are unknown, but it is suspected that it will be an action-unlock secret character because most characters added after their world's initial release are action-unlock secret characters. This may require playing as Moana, Toddler Moana, Maui, or Gramma Tala and finding it, due to all of them finding it in the movie.
The "O" in "Moana" in the movie's logo (right) appears to be a representation of the Heart of Te Fiti.
