The teddy holds a lighthouse in the hand, which is equipped with a battery. The lighthouse has
a light with color change. You have to light the key to the light switch on the link above.
After 15 minutes it switches off automatically. The lighthouse is attached with Velcro on Teddy, so that
you can also take it off easily. So you can use the Teddy as ordinary stuffed animal.
I find the Teddy so sweet that I highly recommend him for any child.
