Crime Prevention Whistle

Looking like an ordinary little brass whistle, this device remotely flips on a lamp within the bakery known as Tasty Geezer Breads. These days that switch acts as a call signal: Saint-Germain's henchwoman, ordered by her superior to run her GPS-fitted exosuit toward the whistle, comes to help whoever sounds it. The signal even broadcasts when blown inside Empty Space.

The whistle's job is purely to trigger that bakery lamp from afar, which in turn flags the alien helper to track its location and respond. Saint-Germain later passed the item to Momo Ayase, who has held onto it since, telling her it would come in handy whenever she landed in danger.

To pay for a fresh exosuit, the henchwoman agreed to assist anyone blowing the whistle toward the shop. Saint-Germain soon handed it to Momo after bumping into her at school. When the Serpo and Mr. Dris later cornered her inside Empty Space, Momo kept blowing it as she fled alongside Okarun, hoping police would notice despite his warning that nobody could; the henchwoman answered instead, grudgingly aiding her old foes. The following day, hemmed in by velociraptors within an Empty Space rendition of the Super Amusement Park, she fastened the whistle onto a balloon, letting its noise pull her pursuers off course while she slipped away.
