Super cute!

My 5 year old is obsessed with Lego builds. This one was the most intricate one he's done so far. He was able to follow the directions for the most part and he put all the pieces together himself except I helped with a few turtle pieces. It says 8 and up but if your kiddo has built before then 5 is fully appropriate. It's so cute!

No one has seen the aquarium set before

My adult son and his GF love, Love, LOVE Lego so when I saw this aquarium set on the desk of my Dr's check out gal. I was so beautiful! When I get home, I immediately looked for it and found Walmart had 3 different sets of it. Because they love aquariums so much, I purchased all three. when they opened the Walmart boxes on Christmas, you'd think they were 7 yrs old!! Jumping and screaming. They too hard never seen these sets and decided date night is going to be building these....

Sea the Beauty!

This set is gorgeous! I had a lot of fun building this set for display in my wife's elementary school office. She loves ocean life and this set has some amazing rare pieces that are beautifully colored and designed. The one downside was attaching some of the sea life to the display.
