An intricate flute carved from solid obsidian is an item of Loric origin. It was left for Number Five in his Loric Chest. 

When used, the Flute lets out a high pitched whistle, so loud and sharp that it is comparable to nails on a chalkboard.

In the Everglades, Five uses the flute while he stared, unblinking, at the winged, three-headed alligator creature. Suddenly, the monster folds it's wings and tucks it's heads against it's chest, as if it was bowing to Five. When he blows it again, the beast is instantly ready for battle again.
