Hit the YouTube icon. It will show a new backdrop. Choose between Vid.1 or Vid. 2. When your watching the video/mini Scratch inside a bigger Scratch, you can hit the back arrow on the bottom to go back to where you choose which video you want to watch. If you want to finish the video, you will know it is done when a red square comes up . Click it and it will go back to video screen. HAVE FUN!!!!!!!!
