With the GraviTrax Junior Starter Set Disney Frozen, children aged 3 and up can immerse themselves in the world of the Ice Queen. They can transform their constructed marble run into their own individual Frozen world. With the figures Anna, Elsa, Olaf, Sven, and additional decorative elements like the Ice Palace, the world of the Ice Queen comes to life. Playing with the figures and decorating the themed worlds encourages creative role play and the imagination of children. Building and play fun are combined. The GraviTrax Junior Starter Set Disney Frozen can be expanded with extension sets, starter sets, or elements. All GraviTrax Junior sets are compatible with each other and are primarily made from renewable resources. GraviTrax Junior addresses age-appropriate learning content. Motor skills and spatial thinking are enhanced through the free design of the marble runs. By exploring the rolling behavior of the marbles, the principle of cause and effect is experienced up close.
