I followed the steps in six tutorials (and Add a Sprite and Add a Backdrop), and put the sprites' performances into a slide-show-type project. If something appears in the wrong place, press one arrow and then the other to hopefully make it disappear.
This uses examples from the Scratch tutorials: “Getting Started” “Change Size” “Glide Around” “Animate a Sprite” “Make It Spin”; This uses Scratch's sprites: Cat, Pufferfish, Bat, Avery Walking, Parrot, Dragon, Robot.
