I loved the concept. The problem is the tail does not fit well at the waist. Yes, they give you a belt, (something that was quickly discarded as being in the way)to cover up where the hip/waist area gaps open. Why not make the tail open and close around the waist area after you stick in the torso? Similar to the way the shoes work? -One good thing about this set, you can use the tail as a doll stand. The wig was not one of their best, but worked OK. My granddaughters were prepared for the lack of torso having purchased add on sets before. Both had to have their own Siren set as it was just too unique to pass up. Would I buy it again knowing what I do now? Yes, but.. The but being none of us liked the hip gap but I think they are still playing with the set and that's good enough for me to give it 4 stars.
The best thing about this create-a-monster is also its downside: the mermaid tail. Alongside the harpy wings, it's one of the most unique body parts among all the create-a-monsters.
And as a bonus: the mermaid tail works on MALE create-a-monsters, too! You can make a merMAN just like you can make a mermaid. It comes with a pink belt to attach to female bodies, and a blue one to attach to male ones.
But, when attached the tail is flimsy at the waist and can come off very easily during play.
The wig is good but looked a little silly (like most create-a-monster wigs) before I poured boiling water on it and styled it properly.
Its arms and hands have great webbing and the tail is really nice. It can stand up on its tail without a doll stand if you position it carefully, but again, it's a bit flimsy and can fall over if you're not careful. Not recommended for kids that can't play carefully.
