Piccolo's Folly (ピッコロ痛恨の大失敗! セルが街に放たれた!, Pikkoro Tsuukon no Dai Shippai! Seru ga Machi ni Hanatareta!) is the fifth episode of the Imperfect Cell Saga and the one hundred forty-fourth overall episode in the uncut Dragon Ball Z series. The episode first aired on June 17, 1992. Its original American air date was October 10, 2000.
Just then, Krillin and Future Trunks fly down to Piccolo and Cell’s battleground. Trying to escape the trio to absorb Android 17 and Android 18, Imperfect Cell powers up a Solar Flare attack, blinding Piccolo, Future Trunks, and Krillin. Cell then flies away, as Piccolo, Future Trunks and Krillin try to get their sight back.
Meanwhile, Gohan, Yamcha, and the others aid Goku in his battle with the deadly heart virus. Goku is looking better each minute yet still sleeping peacefully. Yamcha then talks about Goku beating the Androids when he is fully healed, until Chi-Chi decides to disapprove. Oolong first notices Chi-Chi's anger toward Yamcha trying to get Goku to fight the Androids so soon.
Imperfect Cell now has gotten away from Future Trunks, Piccolo and Krillin and decides to visit the nearest city for some lunch, Nicky Town, but is side tracked by some football players in spiked shoulder pads. Imperfect Cell easily dispatches the Jocks and manages to suck up one of them for power. Then out of the blue, Imperfect Cell catches a glimpse of Vegeta flying toward the extremely high power level. Imperfect Cell sucks up the energy of the remaining players and their coach/driver, then enters the city.
Back at the former battlefield, Piccolo is very furious about letting Imperfect Cell escape, and powers up his Ki madly. Vegeta flies toward Piccolo and asks him “What are you Namek?” Future Trunks then explains to Vegeta that Piccolo has fused with Kami, the Guardian of the Earth, and is now a Super Namek. Vegeta is then jealous of Piccolo for being more powerful than he even as a Super Saiyan.
Ending this episode, Imperfect Cell has thought up a plan to kill the residents in Nicky Town and suck up their energy to empower himself.
