This is my younger son's latest Lego. He's got it on X-mas.
It's more than 1300 pieces an it took him 6 hours to build it non-stop.
LOL, almost a work day. He's building a Lego since he was age four
and this is so far his largest and most complex model. It's about 2' x 2'
with sliding doors, openings hatches, bells and whistles.
