Retailer reviews

Inviting
Very fun and easy to use.
Some pieces were missing.
This is a really cool water robot. My son's imagination can run wild with it.
My son loves the series, and this item is perfect for it.
It was a lot of fun to put together. Many pieces, but a clear instruction manual, as always with LEGO. Great fun to play with afterwards.
