Hilo and his friends learn more about Hilo's past while they battle robots that were buried underground on Earth a thousand years ago.

Everyone's favorite space boy, Hilo, is just settling into life on earth (Bowling? Knock-knock jokes? Outstanding!) when strange portals begin opening up all over town. And holy mackerel! Even stranger creatures are coming through them! But it will take more than a giant mutant chicken, a Viking hippo, a magical warrior cat, or even a few million killer vegetables to stop Team Hilo ... er, won't it? Can Hilo, DJ, and Gina figure out how to send these...
