Digimon Adventure
Summary
A DigiEgg comes out of the Yagami family's computer. Botamon hatches from the egg, and it subsequently digivolves to Koromon. Koromon is an affectionate, bouncy Digimon who likes to kiss Tai and Kari. (Something that Tai doesn't particularly appreciate.) Kari doesn't speak much; she just whistles, although she does talk to Koromon.
Koromon digivolves to a giant Agumon and smashes Mrs. Yagami's car. He and Kari go around generally terrorizing Highton View Terrace for a bit, and then a huge DigiEgg appears in the sky and Parrotmon hatches. Agumon and Parrotmon face off and Agumon digivolves to Greymon. The future Season 1 Digidestined are now watching the battle. Greymon is felled by Parrotmon's attack, and Kari tries to wake him with her whistle. Tai grabs the whistle and blows really hard, until he runs out of air. Greymon's eye opens and he attacks Parrotmon, then both Digimon disappear. The screen fades out and then into the next morning, where most of the street has been reduced to rubble and Kari is yelling for Greymon.
