A starter set in a highly portable "cube" form. Simply press the top handle to automatically unfold the set into a full loop of track! Move Salty along the track and through the docks. To fold the playset back up, just lift the panels and snap them onto the latches on the side of the handle. You can also open the doors and drive through any "cube station" when it is closed. Use the handle to carry your cube station sets wherever you go! Engine stores inside.
