I Bought this for my three year old for christmas. She also had the playmobil christmas in the forest advent calendar and the playmobil penguin enclosure. I think this is a great starter set for girls, an affordable way to see if playmobil suits your child. You get everything you see in the picture, a fairy, unicorn, river, tree, butterfly, dragonfly, swan with three tiny babies , some flowers and a crystal type thing. This is enough to keep my daughter occupied for about 20-30 minutes at a time on it's own, and when I combined it with the forest animals from the advent calendar, she was happy and quiet for an hour at a time. there are tiny tiny pieces (flowers etc) which you will have to reattach from time to time but happily they come off cleanly and don't break.
This is a good set to add to later as your collection grows, you could go down the fairies route, or forest animals or even the mermaid range.
I don't mind joining in playing with the playmobil as its so attractive and nicely made, and I think it inspires creative play in children. Friends that have visited have also been very taken with this, so overall I'd say for less than a tenner you can't go wrong with this toy.
