The official Super Mario Odyssey website has been around for a long time. Some users decided to click around and reported an interesting finding.
If you turn on the music on the website Jump Up, Super Star starts to play but if you turn the music on and off 37 times the website will start playing the Japanese version of the song.
Why 37? It can mean a lot of things but the most obvious explanation is the game release date ( 10 + 27. 10/27 ) or Super Mario‘s age. The character was created in 1985 so that could also be the reason why this exact number.
