Season 16

Dr. Torahiko Kouenji is an eccentric genius who dug out the ancient writings from the oldest layer of the earth. He translated the writings and learned the existence of 13 "Star Pieces" (スターピース, Sutā Pīsu) that had been hidden across the planet. If one should obtain all the Star Pieces, any wish could be granted. To that end, Dr. Kouenji built search robots, known as "B-Robots", to find the Star Pieces. However a trio of such robots, led by Cobrander, were activated without their sleep-education program being completed and thus started to commit bad deeds across the town. Fortunately, a team, composed of three "good" B-Robots, had completed the whole course of sleep-learning, and befriended Yuzuru Kouenji, Dr. Kouenji's grandson. With Yuzuru, and his friends Sayuri Mitaka and Kuranosuke Kichijouji, the three good B-Robots and the gang begin their search of the "Star Pieces" while overcoming the misdeeds of the three "bad" B-Robots.

謎の物体「スターピース」を発見したロボット工学者・高円寺寅彦博士は、6年後のスターピースの力が最も高まる時に備え、スターピース探索のため「ビーロボ」を開発し、姿を消した。 その3年後、寅彦博士の孫である高円寺譲少年のもとに突然現れたビーロボ「カブタック」は、スターピースを探すため高円寺家に居候することになる。 スターピースはへびつかい座を含む13星座に沿って13個存在し、あらゆる願いを叶えると共に、全部集めると素敵なことが起きると言われている。譲の友人や悪者になってしまったビーロボたちも巻き込み、スターピースの争奪戦が始まった。
