Query: We haven't had any trouble with this doll.

I was rather worried about the quality of this product after the low ratings others have given it, but our doll has worked well. Her tail fully retracts and hasn't gotten stuck at all.Something that I didn't realize is that some other Dora dolls(rainbow, coral, starshine, etc.) will tell stories when put in the base that comes with Mermaid Dora.
