From Pikmin Fanon
|Gold! Silver! Bronze!
This article contains information about the non-canon game, Pikmin: Gold/Silver/Bronze, created by GoldPikPik.
The Whistle is used to order pikmin around. But it only works when activated and used by a Gold Pikmin.
The only way to activate a Whistle is to toss a Gold Pikmin on the ground (some people take great pleasure in doing this...).
