Doraemon began as a Japanese manga by Fujiko F. Fujio in 1969, following Nobita, a schoolboy helped by a robotic cat from the 22nd century. The series became a long-running anime and a childhood staple across Asia and Europe, where local dubbed versions used their own opening themes, known in Italy as sigla. Short clips of those themes now circulate online as nostalgic soundboard sounds, shared in anime edits, memes and throwback posts by fans who grew up watching the show.
