If you are a fan of the rotund Italian plumber, you need to stop thinking of him fixing pipes and cleaning drains. Apparently Mario ditched having a proper job ages ago and just like everyone else, he forgot to update his LinkedIn account.
According to his official profile (Japanese) he hasn’t been a plumber for a while. It seems that saving a princess and a whole kingdom several times over is pretty lucrative as he doesn’t hold down a steady day job anymore. Instead, Mario’s “job” is: “All around sporty, whether it’s tennis or baseball, soccer or car racing, he [Mario] does everything cool. As a matter of fact, he also seems to have worked as a plumber a long time ago…”
So from his humble beginnings as a carpenter and as a plumber, Mario is now a celebrity, having a go at Karting and sports and whatever he wants really. As long as it is cool, Mario is there. Wow, fame really changes a person, hey?
