Let me know if you chose one of these ideas. Call your local collage or parks and recks. I don't know the name of the person that ask me about the paint by number sets. I hope this will help and I am sorry I don't remember your name. I hope you get this.
Copyrights are easy.
You have copyrights the second you create an original work. You can register those rights with the U.S. Copyright office if you need to litigate them. Copyrights only cover words and pictures, not things. You may need to patent your idea for real protection. If you have a cute name you'd want to trademark the name.
