History
Chuchu was captured about three years after Yellow's first appearance in the Red, Green & Blue chapter. Yellow captured her in the Viridian Forest, which is also Yellow's birthplace.
Chuchu and Pika produced an egg when Pika spent time with Yellow while Red is relaxing at Mt. Silver. Gold owns the Pichu that came from the egg.
Moves used
Aside from the above, Chuchu also sometimes uses balloons to allow her to Fly.
Trivia
- Although Chuchu is female, the only Pikachu in Generation IV that can legitimately know Fly are all male, coming from Yellow Forest in the Pokéwalker. Conversely, the only Pikachu that can have Surf, like Pika does, are all female.
