- September 9th, 2020Average rating5out of 5 stars5.0SpookyValerian70 | 45-54I would recommend this to a friend!Purchased for: SelfThis is one of my favourite pieces out of the whole of Super Mario Cycle One. I have been eyeing it up on the Lego Website for a couple of weeks and decided that I was not getting the rest of the collection until I got this one. Then I stumbled across it in a local store and it really made my Saturday. We had a bit of a "discussion" about who was building it but unfortunately my 28 year old son won that one so I didn't get to build this set. It looks absolutely wonderful built and is definitely a great display item as well as having play value. This is the only kit with brown base plates but seeing as King Boo is a game boss you can put this anywhere on a course - we've decided that you should battle through the desert and then end up here.

Is there a Luigi in the works? or a Princess Peach?

- August 2nd, 2020Average rating4out of 5 stars4.0LegoSpiny | 14-18I would recommend this to a friend!I purchased this set mainly for the simple yet good looking design of king boo, which I do believe steals the show in this set. The other enemies this set contains (goomba and swoop) are also really faithful reactions of their video game counter parts and after building this set I can say that they are also standouts of this build. The main play set has a nice colour scheme to it which I believe fits the haunted ghost aesthetic really well, and the spiders and cobwebs are nice touches that really bring the build together, unfortunately this sets main play gimmick (which involves raising king boo up and out off a building to stamp on his back) is flawed, you’re supposed to bash Mario against the swoops to raise him up but upon doing so the swoops will fall of the build and don’t appear to be as secure as they were in the apps tutorial video, another complaint is that doing this gently to try not to break it results in a lot of time wasted, which when playing courses means that I will waste a lot of my time picking up around twelve coins when I could have collected a lot more coins elsewhere, and even thou I like the goombas design I believe they don’t fit the theme of the set and enemies such as boos (Mario ghosts) would have fit in better. But overall the set is a nice looking build with great enemies and theming slightly let down by a flawed gimmick.Play ExperienceAverage rating3out of 5 stars3.0Level of DifficultyAverage rating3out of 5 stars3.0Value for MoneyAverage rating3out of 5 stars3.0Build Time: 30 minsBuilding Experience: Advanced LEGO builderWas this helpful?45King Boo and the Haunted Yard Expansion Set
