Lucas Shapes and Sound (SS) displays shapes on the screen. Tap the shape to play a sound. Drag the shape to move in 3D. Double tap the shape for fireworks with sound. Made for my grandsons 2nd birthday. Parent controls require a 3 sec long press to keep kids from accessing the settings. Parents can mute the sound, toggle shape, letters and word display, add word list and add child and parents names for a special message on the screen.
