Adorable, especially for animal lovers!

[This review was collected as part of a promotion.] My son was thrilled to do this set! The instructions were detailed and easy to follow as always and the finished product is so fun. It's a bigger set so it took him a while but he was able to finish it in one night. He loved that it was a unique set and something more realistic that other sets he's gotten in the past - it's definitely more of a display piece. If you or someone you love is an animal lover this is a perfect gift for them. The baby otter is tiny and adorable - you can remove it from the mom or leave it there. Overall this set really is a great value and fun for all ages!

Unique Lego Set

[This review was collected as part of a promotion.] This is such an awesome idea - legos for adults. It's just like a puzzle but Lego form. We have had a family reunion and instead of a puzzle going we had this going! The sea otter is so cute and I loved the blue water. Instructions are great and on par with everything Lego puts out. Totally recommend this to any adult or bright teen/pre-teen with high level Lego skills. High quality pieces.

Hours of fun

[This review was collected as part of a promotion.] I'll be honest, I was a little intimidated when I first saw this set as I haven't played with legos for decades and the design looks complex. I was happy to see it comes with a booklet that guides you through your build, and all the pieces come separated and numbered by bag, which is so convenient. The otter design is so cute and unique. I love the little accent pieces like the little shells and blades of grass. The pieces feel durable and good quality. This is such a great toy for adults who like to work with their hands. I'm going to have hours of entertainment with this one. I highly recommend it!
