BigMouth Dashboard Dancers - Gone Fishin'

How is this related to computers?

Will this work with a MAC? (sorry, couldn’t resist.)

Is this USB powered? Is that why it is under computers?

If this is listed under computers, shouldn’t it be “Gone Phishing”?

Is this like 24" tall or maybe 3" ? BigMouth,does it talk ? Can I put it on the bill of my hat ?
