The 'Mario's Nipples' meme took the internet by storm in September 2017 when Nintendo released promotional footage for Super Mario Odyssey showing the plumber shirtless at Bubblaine. The unexpected inclusion of nipples on Mario's chest sparked an immediate and massive reaction across social media, as fans were both amused and confused by the anatomical detail on a character usually covered in overalls. The meme represents a bizarre moment in gaming history where a minor character design choice became a global talking point. It is frequently used to discuss weird video game facts, 'cursed' images, or the strange level of realism found in family-friendly franchises.
