If you want Pipp Petals softly talking in your ear for an hour, we've got a new official ASMR of her over on a website called Calm.com. Apparently they focus on things like this. They also use Sofia Carson, who will not be voicing her in the series, so this is your last chance to hear that version of her voice!
You can find "Princess for a day" over here. It does require an account.
Thanks to Pipp_petal and Aurablue for the heads up.
