You can't catch Pichu because you have to breed him at the Old Man or Old Lady.
Pretty sure baby Pokemon cannot be found as field Pokemon.
You can't catch pichu in Pokemon emerald,But you can get a male pikachu and a female pikachu or a ditto and breed them, When the egg hatches it will be a pichu
I don't think you can actually catch a pichu but you can catch a pikachu at Viridian Forest and breed it with a ditto.
That is a fairy tale
It's impossible to encounter a wild Pichu in Pokemon Silver. The only way to obtain one is to Breed 2 Pikachu of different gender, or a Pikachu and a ditto, and the Pichu will hatch from their egg.
u have to breed it with pikachu
I'm sorry, but you can't catch Pichu in Pokémon Black / White. To get Pichu on Pokémon Black / White, you need to use Poké Transfer.
You can't, you have to breed Pikachu.
