I used a book called coding projects from scratch from the library, and I copy it. It has lots of cool things. I hope you like my projects. and if you like it, you are free to leave a comment. : ) P.S. Please do not remix this project without my permission. If you would like to remix this project, please message me on my Scratch profile below, where it says "comments." Thanks.
