I ordered two; a few people have asked why. See, these things are interactive; they can play with other ones. I got two so that when I'm not around, she can play with herself.
The back of the package instructs "Laugh and play together!" and "Give her love!"

Batteries were included with both! There were some saf-t pops in the package as well, as a little "thank you" gift.
