If there are options on the side menu, you can use those to customize different parts of your hamster. You can also change the color of something by clicking on it. For example, for the coat, you can customize the length using the side menu and the color by clicking on it. With the ears, the eyes, and the feet, you can't change the shape, you can only change the color, so if it was, say, the ears, you would have to click on the ears to change their color bur there would just be hamster facts in the side menu. With the pattern, the side menu has different options, but clicking on the pattern does nothing. At the end, you can click on the background to change it. Then, you can take a screenshot of your hamster if you want to save it.
