You can change the color of the sprinkles by clicking on the boxes with lines on them, and you can change the shape of the sprinkles by clicking on the assorted shapes next to the sprinkles. Click on the sprinkles to place them on the donut. As for the second page... I hope that it's obvious what to do. Oh, and a word about the drag and drop stuff- click the item once, THEN click and drag.
Everything you experience within this project was made by yours truly.
