Frieza continues to collect the Namekian Dragon Balls, while Vegeta goes to Frieza's ship and slaughters Kui. Meanwhile, Krillin and Gohan battle more of Frieza's minions, but not before they destroy the spaceship they used to reach the planet. Back on Earth, Yajirobe delivers Korin's new batch of Senzu beans to Goku at the hospital. After eating one of the beans, making a complete recovery from his injuries in the process, Goku immediately prepares to journey towards Planet Namek himself. (Source: Wikipedia)
