Marine, Customer ServiceHello, Oh no! That's no fun. We're sorry for the disappointment. It’s rare for a LEGO® set to be missing pieces. If those wayward pieces aren't just hiding on the floor or stuck in the packaging somewhere, we're here to help. Go to LEGO.build/BricksPieces-BV to request replacement parts he used from his own collection.
