This chant is tied to My Neighbor Totoro, the 1988 Studio Ghibli film in which two young sisters befriend the gentle forest spirit Totoro. The repeated name, sung in a playful call-and-response style, mirrors how children in the film summon and greet him. As Ghibli clips spread through YouTube, TikTok, and meme edits, the chant became shorthand for wholesome surprise and childhood nostalgia. It remains popular because it is instantly recognisable even to viewers who have not seen the film, and it quickly sets a warm, magical tone.
