Help with animation

Hello! Hoping someone can help me.

I am making an adventure module game where the "A" button does not serve any practical purpose. Therefore, like the game proceeding this one, I would like to make holding the A button play an animation. It won't do anything, just make the player sprite bob its head. How would I go about doing this?

Any and all help is appreciated, thank you in advance! :)
