The process is simple! You just need to copy Kirby, and make the copy look like you! If you don't know how to copy, you need to click the stamp next to the scissors on the top the screen, and then click on the sprite you want to copy.
Kirby is owned by Nintendo, but this artwork of Kirby was made by me. The yellow and light-blue Kirby is me, SuperScratchMaker001, if you must know.
