## Description

Review: Super fun build and a very cool design - This is a fantastic addition to the Super Mario LEGO collection. The design has such great attention to detail and the build is lots of fun. My four year old and I spent a couple of hours making this together and it was such a great experience - the instructions are very clear and the way the vehicle and Bowser takes shape kept my son constantly excited. Build quality is great and sturdy enough. The wheels move well. The only slight disappointment was the mechanism to push the bombs out of the boot was pretty hit-and-miss - it would benefit from being a longer movement. Otherwise, perfect product, delivered quickly and at a great price.
Review: Lego always great. - Nice set.
