I received product reimbursement in exchange for my honest review. This 3-in-1 Sunken Treasure Mission set is a really great value because it has multiple building opportunities. At first I thought you could make three different components, but was impressed to learn that 3-in-1 means you can make 3 different "scenes" and each "scene" includes multiple components. Plus, three figurines are included in the set. Great gift for the builder that likes to build and rebuild into something completely new.

I received product reimbursement in exchange for my honest review. I gave this set to a 9 year old as a present and he loved it. It was so fun and the quality of the pieces are great. It is a little challenging but that's what makes building these so much fun. It does have a lot of pieces so keep that in mind if you have smaller children around. It allows you to create 3 different scenes all underwater themed. So much fun!!

I received product reimbursement in exchange for my honest review. We have a large Lego collection but this is the first Lego Creator set that we've built. The build offered the right amount of challenge for my 8 year old--she was able to follow the instructions but didn't zoom through it. The octopus and ray were her favorites as they had joints that allow them movement. She especially loved that the octopus had "suction cups" so it could grab this treasure and the ship!
I received product reimbursement in exchange for my honest review. I love this Sunken Treasure Mission Lego set, it's incredibly detailed and challenging for kids 8 years and up. It's a fun underwater theme with a large octopus, submarine, and hidden treasures. The pieces came in four separate plastic sealed bags and they have clear instruction booklets for each section. It's 522 pieces in total, definitely a longer fun project for big kids and adults. The pieces all arrived fully intact without any broken ones.
I received product reimbursement in exchange for my honest review.Lego sets are always super fun to play with or to gift. Our new Lego Creator 3 in 1 Sunken Treasure mission came in a bright yellow box with over 500 pieces. It is designed for kids above 8 years of and gives them a wholesome play experience in creating 3 separate pieces like an octopus, a submersible and a coral reef. This can be variously combined into a lobster, manta ray, a small submarine and even smaller versions of any of these sea creatures and vehicles. Let your imagination go! Pieces were well made in a number of EU states and China and must be kept away from smaller kids to prevent choking. On the whole, Well designed and great fun!
I received product reimbursement in exchange for my honest review. This is the way to go to buy Legos. 3 different sets for the price of 1, yes please! This set sparks so much imagination and play into a world many don’t get to experience. The skeleton is my favorite piece of it all. The scuba machine is pretty cool and exciting too. This will keep kids entertained between the build times and playability once built.
I received product reimbursement in exchange for my honest review. This Lego set is perfect for your child that loves sea life and under water exploration. The 3 in 1 sets are so entertaining and allow for multiple hours of build time. The ability to use your imagination is phenomenal with this. The overall value is amazing considering you get to build three different variations with the same Legos. My child absolutely loves it, and will not get tired of it.
I received product reimbursement in exchange for my honest review. The LEGO Creator 3 in 1 Sunken Treasure Mission is such a cool LEGO set for any ocean lover! My favorite thing about this set is that you can make three different creatures; an octopus, a lobster, and a manta ray! I wouldn’t recommend this set for someone who isn’t familiar with Legos because it can seem complex since there are different creatures in this one set. I can’t wait to display these in my aquarium room!
I received product reimbursement in exchange for my honest review. I love 3 in 1 Lego sets like these, where the main Lego object transforms into different animals. I especially like how unique this Lego set is with the submarine as it's very different from any other under water set. The instructional book and all the clearly labeled packed bags make it easy to construct and stay organized. Such a fun Lego set promoting children's creativity and use of their imagination. Highly recommend this set to others!
