Super Mario 64 was released by Nintendo in 1996 as a launch title for the Nintendo 64, and its castle paintings became one of the game's most iconic ideas, with each painting serving as a doorway to a different course. The short jingle that accompanies Mario's dive into a painting has since become shorthand online for entering another world. It is widely reused in gameplay videos, nostalgia edits, and meme transitions because it instantly recalls the feeling of discovering a hidden level behind a picture on the wall.
