Doraemon began as a manga by Fujiko F. Fujio in 1969 and became a long running anime about a robot cat from the future helping Nobita with futuristic gadgets. The Anywhere Door, called Dokodemo Door in Japanese, is one of his most famous tools and appears throughout the series and films. Clips of its opening sound spread through anime edits, Spanish language soundboards and short video memes, where puerta magica remains the common search term among fans who grew up with the dubbed version.
