Silky tags, soft buttons, and crinkly wings encourage babies to explore textures. Hear the firefly say that you light up its world, or listen to soothing and catchy melodies by pressing the heart and music buttons. Press the leaf button to hear peaceful sound effects of wind, water, and animals. Help them fly off to dreamland with calming lights and sounds by setting the timer to 15, 30, or 45 minutes and placing the little bug on a shelf or dresser. Designed for children from birth. Requires 2 AAA batteries. Batteries are included for demonstration purposes only. Fresh batteries are recommended for regular use.
