Happy Naru circulated online as a short soundboard clip named for its own repeated lyric, with listeners searching for it by the happi happi phrase rather than by a show or artist. Its spread came from short form edits where the loop could be pasted over cute characters, pets and celebration moments without needing any context. Because the chant is instantly recognisable and easy to time to a reaction, it stayed in use as a go to happy meme sound long after similar novelty clips faded from feeds.
