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.
