An answer from my 8 year old who just brought furby boom home with her Christmas money, $60:
The toy is not a dud. It is good because if she wants a furby boom, it hatches eggs. Regular furbies eat, dance, and sing. If you get certain types, they fart and burp. A fruby boom warns you before farting.
Basically, the toy is okay for 9 -10 year old because the commercial shows a 11 year old kid getting a furby on her ipad.
The app actually makes the furby dance, rock and roll, sing, and makes them go to sleep.
Actually Gamma G, my daughter has a regular furby and a furby boom. Both which she purchased with her dad while I was not there. They annoy me, but she seems to be entertained enough to buy a second one.
*****EDIT*****
My daughter and husband just came home and she is p'd off! She walked in and said, do you know what furby has turned in to? I said, I boy? She says he is really rude and won't stop.
I asked what were you doing to make furby act like a boy, but she says nothing.
Mind you, she was at hockey camp, out with dad...need I say more.
She is trying to tell furby she wants the princess she used to be, all I could say was, I get it...I understand.
