These guys in London made Mario Kart happen in real life! They dressed up as the video game characters and raced around Westfield like they were playing the Coconut Mall level. Because why the hell not.
It even comes complete with props! Notice the dude that played Mario threw a banana behind him at 1:16 in.
Evening Standard will hit you with more info here. And possibly a blue shell.
So who wants to dress up and race around Opry Mills with me? I get to be Yoshi!!
