What Is The Easiest Way To Make An Animated Object?

I want to create my own object like animals and stuff. What's the easiest way to do it? Illustrator? Photoshop? Or other software?

 

There's no real easy way to do it, but if you're on a mac I recommend Pixelmator.

 

try application called "BrashMonkey Spriter"

 

Choose one what you are confortable with it, but vor detailed stuff i can vote for Illustrator
