Press the green flag to start the animation. Also, press the sprites (except me) for some random surprise.
I'm proud of making the sprite "walk" by hiding one sprite and showing another. I like how I did it because it looks more "realistic" than just hovering the sprite to another place. The part I got stuck on was what things I should share with the Scratch community. There's just so many choices I could have put in, and I take long with decisions. I got unstuck by just keeping it simple with my favorite color, food, and book author.
