Nintendo Labo was Nintendo's Switch accessory line that let players fold cardboard into working Toy-Con controllers, piano keyboards and fishing rods, launching in 2018. Its playful, hands-on spirit made it a natural source of jokes and edits, especially among creators who liked mixing real cardboard builds with game footage. Short clips labelled with a name like Boris tend to circulate on soundboards as quick reaction sounds rather than official game audio, and they survive because the Labo reference is instantly understood by Nintendo fans. The combination of nostalgia, silliness and short length keeps it useful for memes.
