I am an elf who has the pleasure of buying gifts for a 2-year-old boy. His mom says he'd love an "interactive DVD". Since my *baby* is 20 years old, I'm not familiar with interactive DVDs for kids. (The only thing I could think of was Scene It, the game, and I'm sure that's not what she's talking about. I did a search on amazon.com and well.... I'm sure that's not what she's talking about either...) Can anyone help? Thanks!
