AppAdvice has teamed up with Banzai Labs in order to offer you a chance to win one of 20 promo codes for InstaPal ($.99) for iPhone, iPod touch, and iPad.

InstaPal is a wacky entertainment app that is able to your photos into animated talking characters that repeat what you say in different voices.

InstaPal's Mouth Adjustment Option

The animation process begins with importing a photo from your library or taking a new one using your iDevice’s built-in camera. You can then move and scale your photo to focus on the face of your subject.

After your subject is all framed up, tapping the orange edit button will allow you to choose from the four included mouth shapes. All of the mouth shapes feature circular handles that allow you to adjust where your image breaks to create the mouth animation.

With your mouth all set up, the last step is to choose one of the three voice modifiers. You can then speak into your iDevice and watch your photo come to life with a hilarious new voice. It’s that simple.

InstaPal‘s amusing mouth animations are reminiscent to South Park‘s, which is great if you have always wanted to create your own characters. InstaPal‘s only real shortcoming is that you are currently unable to record animations, but hopefully it will be an option in the future.
