I personally think that this is one of the COOLEST DOLLHOUSES EVER!!!! When you ring the doorbell, the house comes alive! The Caring Corners - Mrs. Goodbee Interactive Dollhouse has 12 rooms to explore and allows for 2 children to play with together. When the house unfolds, it has 6 rooms on each side. It does take batteries, but only 3 AAA. This house is currently 1/2 price on Amazon!!! It's currently $41.99! We bought ours from Once Upon A Child for $40. Definitely worth every penny!
