Whistle

In Digimon Adventure and some of its related anime productions, Yagami Hikari owns a whistle (笛 Fue) that hangs on a cord around her neck. Its sound is a recurring motif, and its use by both Hikari and her brother, Yagami Taichi, is an occasional minor plot point.

======
Yagami Hikari already owns this whistle as a toddler in 1995. She mostly communicates with Yagami Taichi by blowing it at different pitches and speeds to convey her feelings. When Botamon flees under the children's bed after hatching, Hikari uses it to strike a rapport with Botamon: she blows the whistle a number of times, Botamon responds by blowing bubbles the same number of times. After Botamon evolves into Koromon, she begins speaking verbally with him.
At the climax of the fight between Koromon (evolved into Greymon) and Parrotmon, when Parrotmon knocks Greymon out, Hikari tries to blow the whistle, but is unable to because she is crying too hard and out of breath. Taichi sees this and gets an idea, and takes it from her and blows it himself with all of his might. The sound of the whistle reverberates all around Hikarigaoka and is noticed by all of the children who are watching the fight. In response, Greymon wakes up and attacks Parrotmon with a that sends them both back to the Digital World.
======
Yagami Hikari always wears this whistle around her neck.
When Whamon is ferrying the Chosen Children under the sea to escape Metal Seadramon, at Izumi Kōshirō's request, Hikari blows her whistle as hard as she can to create a makeshift pulse. Kōshirō and Whamon use the echo of her whistle to locate an undersea tunnel to continue on through. However, Metal Seadramon also hears the whistle and follows the sound to track down Whamon.
After the defeat of Apocalymon, as the Chosen Children say their goodbyes to their partner Digimon, Hikari gives the whistle to Tailmon. Hikari remarks that it looks good on her.
======
The whistle does not appear in the present-day story. However, when Imperialdramon: Paladin Mode finishes off Armagemon, the blast of the whistle is heard around Tokyo Bay, and the characters respond to it. (When the whistle blast begins, the film replays the shot from the Digimon Adventure short in which Yagami Taichi, age seven, blows it.)
======
After the Reboot, some of the Chosen Children hear the sound of the whistle from somewhere far away, reminding them of their partner Digimon. When they enter the Digital World, they again hear its sound, and follow it to a clearing, where they find Tokomon playing with it. Nyaromon insists that Tokomon return it and that it is her whistle. Takaishi Takeru uses the whistle as a way to break the ice with Tokomon and talk to him.
When Hikari approaches Nyaromon and tries to introduce herself, Nyaromon remarks that Hikari smells exactly like the whistle and that she finds the scent calming.
======
In Never-Land, the Chosen Children return to the appearances that they had as children on their first adventure while they are under Menoa Bellucci's control, so Yagami Hikari is once again wearing her whistle. When all the Chosen Children and partner Digimon gang up on Yagami Taichi and Ishida Yamato, Taichi desperately forces his way through all of them, grabs the whistle from Hikari, and blows it with all of his might, just as he had done back in 1995. This snaps the children and partner Digimon out of it and returns the children to their present-day selves, at which point the whistle disappears again.
