The line comes from Lindo Balão Azul, a Brazilian children's song from the early 1980s written for a television special inspired by Sítio do Picapau Amarelo. Its image of riding a comet tail through the Milky Way made the chorus instantly memorable for a generation who grew up with the song on TV and records. It later stayed in circulation through covers, school performances and nostalgic posts online, and the opening line now appears on its own as a shorthand for dreamy departure, imagination and childhood wonder in Brazilian edits.
