It can be heard from Adventures of Mini-Goddess (Aa! Megami-sama!: Chichaitte Koto wa Benri da ne), The Real Ghostbusters, Yamataro Comes Back, and Mugen Train from Demon Slayer. I found out that there was high quality of this whistle taken from Episode 44 of Adventures of Mini-Goddess. I think is rare anime sound effect.
