The Little Mermaid is one of my daughter's (and her friends) favorite Disney movies. While her all-time favorite movie features princess Belle in Beauty and the Beast - The Little Mermaid scores very high on the list. The Lego Duplo Ariel' Undersea Castle features Ariel and her friends Flounder and Sebastian. A bit of a word of caution - while it is a fun playset it is also a little more advanced. So while a 3 year old may struggle with out the help of a parent - they still will enjoy acting out adventures featuring Ariel and her friends.

Notes-

- Includes Ariel, Flounder and a block with Sebastian on it. Ariel's arms and head moves - and she bends at the waist. She also has the ability to snapped into place in both the standing and sitting position.

- The castle scene that is pictured on the box is pretty difficult to make. Children under 5 will struggle making anything that resembles the castle on the box

- Comes with a swing, slide, treasure chest, and treasures that can be placed around Ariel's castle.

- While the playset is rather complex there are lots of castle designs that can be created.

Final Verdict - One of the more difficult Lego Duplo sets, however with the help of a parent most fans of The Little Mermaid will enjoy creating scenes with the Dupo blocks and playing with Ariel and her friends.

Our daughter loves this Duplo set! It comes with a decent array of pieces, including a number of "special" shapes that are really a lot of fun and add to the building options. The only real complaint I have is that the transparent blocks (water look?) don't quite have the same fit with the other blocks. As a result, they don't attach well and structures fail easily where these blocks are used. Still... it's a winner!

Great addition to the princess castle. Granddaughter loves the swing for Ariel. Easy for a 4 year old to put together.

This lego set was bought as a gift for my daughter, and she absolutely loves it! The blocks are big enough for her to actually enjoy playing with, yet not so huge to where it's a babyish toy. She's 3, so this was perfect for her. She loves the Arial design and still plays with this daily. Great product, great price!

I took a gamble buying these on a lightning deal for my 1 almost 2 year old because I had no idea how this would be received by her. This ended up being one of her very favorite and most played with Christmas gifts surprisingly. At this point, she doesn't know how to build the structures, but she does enjoy helping me put them together, letting the characters slide or swing, then tearing apart the structure. As a side note, the design of the slide and the swing they provided is terrible. The swing tips right over and the slide constantly came off of the lego it was attached to. I adjusted the design easily and the swing and slide will actually stay upright when my little one plays with them. The lego's in general fit together fairly loosely and I do have trouble keeping the structures together no matter what. Also, the swing constantly comes out of the piece it is attached to. I may end up putting a little tape over the top to keep it in place.

If your child is still mouthing things, I would recommend taking away the little flowers that are included. They could certainly pose a choking hazard. Some of the other parts are also smallish for a child under 3, so make sure to use caution if you think your child might put them in their mouth.

We got this as a gift for our 3-year-old friend and she loved it... and we played at it with her house and my son really liked it too! You can't go wrong with Duplo and this has some fun "accessories" to add to the basic block kits! Some people complain that it's expensive for these kind of kits, especially being Disney, but for a Little Mermaid-Loving-Duplo-Adoring-Kid, you can't go wrong, and at Amazon it's always a good price!

This is what it is. My kids like legos. I bought this for my four year old daughter's birthday. She was happy because it combined her love of princesses and legos. However, after about an hour of putting it together, the fun is now over and it rests with the rest of our lego collections. I don't really mind, but will never understand why legos are so expensive.

My 2-year old really enjoyed this set! Nice colors and enough pieces to make different configurations. My daughter also loved playing with the Ariel and Flounder figures. Duplo items are perfect for this age!

Thankfully, this was not a gift because the box arrived scratched and marked and included a price tag which read "Walmart $21.00". (I paid around $25 on amazon.)
