Back in a day we played with it with my cousins when they were kids (and I was teenager). There was some big insect like hornet or at least wasp with that scary noise. The younger one was afraid of it to the point he would run away, screaming and crying (no exaggeration here). And the older one loved to scary the shit out of his younger bro to the point he still mentions it with a smile sometimes even though they’re now 20+
