While meditating beside a waterfall, Piccolo is approached by Gohan and Icarus, with Gohan showing Piccolo a tune he has just learned to whistle. To his shock, Piccolo finds the noise excruciatingly painful due to his enhanced Namekian hearing, and angrily orders Gohan to stop. As Gohan apologizes to Piccolo, they both soon sense something coming from space. Meanwhile, at the Capsule Corporation compound, Bulma and her father discover that a meteor is heading toward the Earth and will most likely destroy the planet upon impact. Amidst mass panic throughout the Earth, Goku and Krillin rush to intercept the meteor, blasting it with ''Kamehameha'' waves, but fail to damage it. The meteor, however, does not hit Earth, instead passing it and exploding in orbit. When the dust clears, a strange building-like spaceship is present on the Earth.
