"The build was challenging. It’s not really made for 8 and up. The finishing model was nice. The first time I put it in the water the boat floated, but the second time it floated for 30 seconds than sank. When I took it out of the water. It was dripping water but then the bottom of the green boat pieces fell off. I was surprised! Now that is dumb that the bottom of the boat does that. Think of a better design lego!!"
