Giant Whistle

The Giant Whistle is a power skill which summons a hand from the Giant to smash the strongest nearby enemy.

Trivia

 * Because the blueprint for this item is only dropped by the Giant, it is technically an item exclusive to the Rise of the Giant DLC, even though it was added to the game in v1.4.
 * It may be a reference to a dog whistle, which are used to summon pet dogs. In this case, the Giant is serving the Beheaded.
 * It may be a reference to the Old Bell in Don't Starve, which calls down a giant leg to do damage in the area.
