I just did this on Saturday! I had Cinderella call my in-laws house during DD's 4th birthday party to wish her a happy birthday. She was thrilled! Afterward she said that she loved the call but would love to Mulan to call. What she didn't know is that I already had Mulan scheduled to call on her actual birthday (the 10th). I know she will be so excited. $4.98 seems like a small price to pay to bring that kind of joy!
