Doraemon began as a Japanese manga created by Fujiko F. Fujio in 1969 and became a long running anime about a robotic cat from the future sent to help schoolboy Nobita. Short clips of its cartoon cues spread widely through YouTube edits, fan videos and soundboards, where the appear jingle became shorthand for a sudden, helpful arrival. Because the character is linked to futuristic gadgets and impossible solutions, creators reuse the sound whenever something cute or unexpected materialises out of nowhere.
