Bulma is caught in a trap, and several human-looking aliens (with a hairstyle similar to Gohan's old hairstyle) are about to shoot Gohan and Krillin, mistaking them for followers of the evil Frieza. Then, the ship runs into an asteroid storm. A huge chunk of the ship falls and is about to crush several of the invisible spaceship people when Gohan and Krillin save them by holding the chunk up. Bulma gets to the cockpit where she flies the ship out of the asteroid storm. Once they are out of danger, Zeshin, one of the invisible spaceship people, and most of the others try to shoot them again, but their leader tells them that since they saved them they cannot work for Frieza. Zeshin remembers when Cui led an army of Frieza's soldiers to their home planet and destroyed it, and thinks that Frieza's men would never help them, so he is convinced that they do not work for Frieza, and they allow them to continue their trip to Namek.
Meanwhile, Vegeta arrives on Planet Frieza 79. Apparently Frieza just left. Seeing him severely injured, Frieza's soldiers place him in the rejuvenation tank to heal him. Meanwhile, Bulma, Krillin, and Gohan arrive on Planet Namek. Before Bulma can check the Dragon Radar, however, the ship falls off a cliff, knocking them unconscious. When they wake up, they see two Nameks named Raiti and Zaacro, who decide to help them find the Dragon Balls. The first Dragon Ball is in a lake, and Raiti finds it under a boulder. The second Dragon Ball is inside a cave. Bulma opens a coffin and finds it, but it is in the mouth of a skull, which freaks everyone out. Now they have two Dragon Balls, and have five more to find.
- This is the first time that Frieza's name is mentioned in Dragon Ball Z.
- Cui makes his first appearance, although it was in a flashback told by Zeshin. His first true appearance was in Who's Who?.
- The title appears to refer to the Invisible Spaceship people, but may also refer to Raiti and Zaacro, as they are later revealed to be enemies.
- This is one of the few times Vegeta refers to Goku by his Earth given name.
