Sending much Aloha.

yeh she is definitely a fox but she needs an exorcist.
Come on guys, this is not the forum to make anatomic jokes considered offensive by many people we would like to feel welcome on this forum, right?
Having said that, most of the time I could not hear the over tones on my small little computer speakers. The times I did hear them were pretty interesting.
Also, from her face and body language, it looked fairly uncomfortable to generate those dual tones simultaneously.
