Mario very regularly has a huge smile on his face, whether he's stomping on sentient flowers or chowing down magical mushrooms, but there's one unused area in Super Mario Galaxy 2 that makes our already loveable plumber go into a somersaulting frenzy. And, seriously, I've never heard Mario sound so happy.
Super dedicated blogger and series archivist Supper Mario Broth recently found that Super Mario Galaxy 2 has been hiding an "unused 'joyful zone' area" for all these years. Should Mario step foot into the zone, he gets the zoomies and the giggles or, more plainly, he'll uncontrollably run and somersault and scream "Yahoo!" without stopping.
In a hilarious experiment, Supper Mario Broth recently "enveloped the entirety of Starship Mario in a joyful zone for demonstrative purposes." The result is incredible - you can watch it down below. I dare you not to smile, dear reader.

Rosalina and the Lumas are apparently immune to the joyful bug. Not everyone appreciates jumping high and being obnoxious about it as much as Mario, to be fair, but still.
In the game's files, the zone is apparently called "CometFireDanceArea," perhaps suggesting the mechanic was once intended for one of Super Mario Galaxy 2's Prankster Comets - special missions that would modify a pre-existing level with fun rules, asking you to race your cosmic doppelganger or beat a boss with one health point, say. I can definitely imagine a comet that would make Mario complete levels without stopping or jumping normally.
