Nobody talks about this one. A single perfect minute where Alberto Shiroma's melody does all the heavy lifting, a kids' song that refuses to condescend to its audience, built on the kind of hook that survives thirty years of playground repetition. The animation exists only to get out of the way of the music. If you've ever wondered what happens when a song is so good it doesn't need anything else, this is the answer.

Alberto Shiroma's song "Ninja Negizou" is set to a music video, released as a single episode. It was broadcast on Minna no Uta, a program on NHK. The native title is 忍者ネギ蔵.
