Retailer reviews
Summarized retailer review data when available.
This Lego set is seriously the cutest! My seven year old daughter put it together pretty easily and is obsessed with the little Lego characters. She even takes them in the bath and brings them everywhere. The only tricky part was the swing. It is a bit off balance so every time she tried to actually swing the character it would fall apart. It got so frustrating that we finally just glued it together. Other than that it has been a huge hit!
I recently gifted the Lego Ariel’s Magical Underwater Palace to my three-year-old for Christmas, and it was a huge hit! She had so much fun building it with her nine-year-old sister, which made it a wonderful bonding experience. The set is perfect for younger kids since the pieces are larger than those in typical Lego sets for older children, making it easier for little hands to manage. My only complaint is that the bags weren’t labeled or organized according to the instructions. We had to dump all the bags into one pile because they were completely mixed up, which added a bit of unnecessary frustration. Despite that, it’s a beautiful set with bright, fun colors and great details. Both of my kids loved it, and it’s been a magical addition to their playtime!
When the LEGO DUPLO Disney Ariel's Magical Underwater Palace set was taken out of the box, two children were immediately very happy! As a big Disney fan myself, I enjoy sharing my passion with my children. This set was fun to build for both my 2.5-year-old daughter and my 4-year-old son. It was nice to see them working together on this. Because it is a large set, there was enough to build, so they didn't have any disagreements about who could hold what. My daughter particularly liked a few pieces, such as the hairbrush (harensnaaier), guitar, and swing. My son especially liked the slide, the palace towers, and the water plants! It is a beautiful, colorful set that stimulates their imagination. They have already had a lot of fun playing with it together and they haven't gotten tired of it yet!
A lovely gift to put under the Christmas tree! Our daughter has already had a lot of fun playing with it. The material is sturdy and easy to maintain. A great way to start with LEGO. As far as we're concerned, it's a great recommendation!
This set is highly recommended for (very) young children. When this set arrived, my 3 and 5-year-old daughters were immediately enthusiastic. The cheerful colors encourage immediate building, and the theme also invites multiple play sessions. Assembling the set is challenging for a 2/3-year-old, but with a slightly older child, it works perfectly. However, the slide and swing are also very popular, as is the rotating disc that makes the princesses "dance". Overall, a highly recommended set.
My family absolutely adored this set! I must begin by saying these may be the most endearing Lego characters I've ever laid eyes on - they're incredibly detailed. I applaud Duplo for prioritizing safety for younger users. Lego consistently inspires kids to unlock their creative potential, hone their hand-eye coordination, and bring joy to people of all ages through ingenious designs. This set was a breeze to assemble and provided endless entertainment.
This set is great for any Little Mermaid or just mermaid fans in general. My daughter has a ton of Duplo sets and was soo excited to put this one together. Although she just turned 7, I still prefer these legos as they are a little bigger and easier to put together and take apart. She’s already added in her other Ariel sets and made a big underwater kingdom. Very much pleased with this!
I helped my daughter put it together. Overall, it was ok, but too pricey for what you get. Disappointed that Flounder wasn't included in the set, because he's an original.
My child loves this Lego set! I didn’t realize how large the set would be overall but that’s okay! It’s for ages 2 and up so littles can join in on the building as well. It’s great!
First thing I noticed was the bags were not labeled which frustrated my 5 year old. The prices for each step were mixed into different bags. Once assembled it is very bright which pulls in the children's attention.
This set is great for any little Ariel/Little Mermaid fan (set for ages 2+). The Duplo sets are perfect for little ones with small hands who like to put toys in their mouth. No small parts to choke on. Since the blocks are large it’s a great way for little ones to learn to build. This is a larger set with lots of different ways to play. Includes 2 figures (Ariel and Fernie), Sebastian, a guitar, a brush, a camera, a cup, 2 tables, and a treasure chest, as well as the castle and swing set. My daughter is 8 years old, and while she’s a little old for Duplos since she’s old enough to play with regular LEGOs, she really likes playing with this set. She loves Ariel/The Little Mermaid (the movies and shows). This particular set retails for $79.99, which seems a little much in my opinion even if this is a larger play set. *I received this item complimentary from Influenster for my honest review.*
