Let it go and sing along with this Content Tonie - Frozen from Tonies, Princess Elsa brings us the story of a kingdom trapped in perpetual winter and 4 of its most famous songs. Simply place Elsa on top of the Toniebox (*sold separately) and listen to the audio play for up to 24 minutes. Tonies are robust, hand painted characters that contain the content of audio books, songs and stories. Tonies work with a Toniebox, the innovative portable music player system that combines playing, learning and listening. It's screen-free and easy for children to operate. Placing Tonies audio characters on the Toniebox begins playback automatically and taking them off stops it. Pressing the ears changes the volume. Tapping the sides changes tracks and the fast-forward or rewind function is activated by tilting the Toniebox.
