A menu will prompt you to choose between the Local Gallery (the objects you have currently on your computer) and, the Web Gallery (the objects you can get from the Alice website). Most of the objects from the web should be on your computer. If your internet connect is slow remember, the objects are large and could take a long time to download; so, choose the Local Gallery option. The Skater can be found under the people folder. Click and drag her into the world pane.The cones and the hole are in the shapes gallery. Drag the cone three times into the world pane and do the same for the circle.
