They're Alive!
Ventriloquism is not easy. Keeping your mouth still, while still conveying emotions and making your puppet speak and move, is tricky. It takes a lot of practice. I tend to practice the speaking part when I'm walking my dog (in less populated areas), or sometimes when I'm driving.
It is all worth it though. If your puppet is alive and real in the mind of the audience (even the adults), then you understand why you spent so long practicing and perfecting your act.
I've mentioned before, that after a show, sometimes a little boy or girl will come up and give me a drawing or a gift because they've enjoyed the show so much, but most of the time those gifts are for Chester or Harris.
Adding animated characters to my show definitely changed things for the better and when I realised how much the audiences buy into these characters, the more I feel genuine joy, and just a little bit of pride. I think that's allowed.
