The horn used to alert people, of the dangerous grenades that may be lurking in your household with you not being aware of it.
There were grenades lurking around the house, i had to alert my friends before they were attacked! so i blew in to the grenade whistle hoping that where ever my friends were, they would be aware that grenades are around.
