All you have to do is press the green flag. This is a Scratch about 2 people talking to each other about saving the world. One person doesn't get why it's important to do that, so the other person explains it to her. Turn on your audio because their is sound. This is for if you are new and not. ---> you can press the blue button on the upper right hand corner to 'see inside' of my scratch to see how I made this. This is my first Scratch.
