We love a good flashmob here at Nintendo Life Towers - unless it's threatening to make us late for our train ride home, of course. The crazy thrill seekers on YouTube channel Base37 certainly know how to do a flashmob in style, as they recently descended on London's Westfield Shopping Mall armed with motorised go-karts in a range of Mario-themed fancy dress costumes.
Watch the video below to see the mayhem unfold before your very eyes. There are dirty tricks with banana skins, a nightmarish Donkey Kong and a run-in with the police at the end. Clearly London's mall security is somewhat jumpier than that of Isle Delfino!
