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&rsquo;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&rsquo;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&rsquo;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.</span> <div class="bvseo-pubdate">Date published: 2020-08-02</div> <meta itemprop="datePublished" content="2020-08-02" /> </div> </div> <script type="text/javascript"> if (document.getElementById('bvseo-reviewsSection')) { document.getElementById('bvseo-reviewsSection').style.display = 'none'; } </script> <!--end-reviews--> <ul id="BVSEO_meta" style="display:none!important"> <li data-bvseo="bvDateModified">y_2025, m_8, d_2, h_5</li> <li data-bvseo="ps">bvseo_bulk, prod_bvrr, vn_bulk_3.0.42</li> <li data-bvseo="cp">cp_2, bvpage2n</li> <li data-bvseo="co">co_hasreviews, tv_37, tr_11</li> <li data-bvseo="cf">loc_en_CA, sid_44864AC3, prod, sort_[SortEntry(order=SUBMISSION_TIME, direction=DESCENDING)]</li> <li data-bvseo="diagnostics">clientName_toysrus-ca</li> </ul> <!--end-bvseo-reviews--> <ul id="BVSEOSDK_meta" style="display: none !important;"> <li data-bvseo="sdk">bvseo_sdk, dw_cartridge, 18.2.0, p_sdk_3.2.0</li> <li data-bvseo="sp_mt">CLOUD, getReviews, 5ms</li> <li data-bvseo="ct_st">reviews, product</li> </ul>
