Buying a present - In a toy shop

Good morning. Perhaps you can advise me... Yes, ma'am. I'm looking for a toy for my niece. Oh, yes... how old is she? She'll be seven years old on Sunday. Skateboards are still very popular. Hmm, I don't want her to hurt herself. What about a Barbie Doll set? I don't think so. She has many Barbie Dolls. Have you got anything educational? You see, she's a very intelligent girl. I've got the perfect thing! A do-it-yourself kit where you can build your own Barbie Doll who rides a skateboard!
