animate

What program can I use to animate my character for my Outro? Is there somehow I can Animate my character to make him float and move his arms and his hair a little? Not entirely sure how the picture itself should look but I have made an example below. Any suggestions would be appreciated!

Hey! I'm looking for an animated intro for my videos, and I've already got the basic idea of what I want, I just suck at animating and stuff like that, haha! I need someone to create the intro for me. I will give credit to you if you agree to make it. Thanks! <3
