Fisher-Price is launching a new "We Did It!" Dora doll. Fisher-Price introduced its first "We Did It!" Dora Doll in 2002 and it became one of the bestselling toys of the holiday season. The original Dora doll sang the "We Did It" song and swayed back and forth to the music. This year, Dora moves her arms, swings her long hair and swivels her body. Dora also teaches kids the steps to her signature dance and engages them with four interactive play modes. The new interactive Dora doll is meant for children ages 3 years and older. The MSRP is $39.99.
