RotoBall Idea

My Rotoball idea is amazing. The ball will first enter from the left in the shape of a bird. It will carry a message that the character will read, no one know what it will be like. After that, I want the

ball to transform into a kid's jumping ball

and have my character jump and jump on it, then make it small and let it transform into a bird. The bird will fly around the character's head. Finaly the character will write "I love you on a paper" and send it with the bird.
