Serialized in Gakken's "-th Grade Science" magazines from 1978-1980, this is the precursor to Ishinomori's later gag comedy work Chikkun Takkun. This early version does not feature the antagonist characters "Dr. Bell" or "Giji Giji" seen in Chikkun Takkun, but instead features an episodic format focused upon a different educational topic each chapter.
