First the child has to solve this 48 piece giant floor jigsaw (45 x 60cm). When complete it will reveal the Grand Hall from the Cinderella animation.
Once constructed, wind up the included prince and princess figurine and it will 'waltz' around the scene when placed into the pre-cut tracks. This Disney Princess Floor Children'sPuzzle also features a sound box which, plays an elegant and beautiful melody .
This Musical Floor Puzzle contains 48 large jigsaw pieces , a musical sound box and 2 wind up figures of a princess and princess which 'dance' around the scene. Encourage shape recognition and problem solving among children aged 3 and up with the Disney Princess Wiz Around Musical Floor Puzzle.
