Vegeta has recovered, and with no one watching him, he breaks out of his medical chamber and hides. He creates a diversion to get Frieza and Zarbon away from the five Dragon Balls. He goes into the main control room that contains the Dragon Balls, blasts a hole in the ship, and escapes. Furious over the loss of the Dragon Balls, Frieza orders Zarbon to find Vegeta and the Dragon Balls in one hour, or he will die. Vegeta finds a suitable hiding spot for the five Dragon Balls. He knows that Frieza and his henchmen have no scouters and can't sense energy signals, so they won't be able to find the five balls without combing the entire surface of the planet.
