Using the website is a good tool to try and figue how much creating an animal would costs. We tend to average anywhere from $35-$50 an animal. My kids tend to get an outfit as well as a voicebox in addition to their stiffed animals. The first few stuffed animals from BAB even got shoes, but they kept falling off and it just wasn't as huggable with hard shoes on, so we haven't bought shoes in a while.
If you have a local BAB, stop by. They are running a game piece promo and you cna win lost of different prizes. We stopped by yesterday just window shopping and dd saw a High school musical t-shirt $6. At the checkout counter were individual game pieces. Dd won a cali bracelet and charm and ds won a free animal. He's saving his free animal certificate to use at downtown disney for our next trip in Oct.
