This hat has LED lights. The battery is inside the hat and can be removed. If the battery runs out, you can replace the battery to use it.
Touch a small hard square above the squeeze balls. Pull out the small insulating card and the button is on one side of the square. Press once for quick flash, again for slow flash, then solid-on, then off. If you don't know how to use it, please don't hesitate to contact us.
By pressing the paws of the hat, the two ears of the hat can jump up and down.
