Why does my Furby 2012 sleep with its eyes open?

If your Furby 2012 is sleeping with its eyes open, it may be due to a malfunction or a glitch in its sensors. Furbies are designed to close their eyes when they enter sleep mode, so if this isn't happening, try resetting the device by turning it off and removing the batteries for a few minutes before reinserting them. If the issue persists, it might indicate a deeper hardware problem that may require repair or replacement.
