Annabelle discovers an animal bone in the woods and decides to make it her new plaything. But nature ends up moving Annabelle in mysterious ways. At first, Boney, as Annabelle names him, makes the perfect companion. While Mom is busy with the baby, Boney and Annabelle share a meal, play at the park, and share a bedtime story before Annabelle tucks Boney into his shoebox-bed for the night. But when creatures run wild through her dreams, Annabelle considers for the first time where Boney really belongs.
