This Merissa Doll Barbie Fairytopia Mermaidia is great because the tail is attatched, and therefore, doesn't fall off. My daughter is thrilled. This doll is pretty and sturdy. The "tatoos" don't show up very well, which is why I didn't give this product 5 stars. But, parents, if you are looking for a mermaid for the tub, this one is a great buy--I think I paid $[...] (the others, with a detatchable tail, were $[...]!).
