Fishing in the Route 4 waterpath by using old rod =)
You get Squirtle as one of the starter pokemon.
Squirtle can be acquired by trading for one from a Firered/Leafgreen.
Squirtle is only obtainable if you chose it at the beginning of the game you must get one from another firered or leafgreen then give it to your firered and then you can finish your pokedex.
You can't.
firered and leafgreen version
bulbasaur, squirtle and charmander
you have to get squirtle as your starter
If you picked Squirtle as starter, you can evolve your Squirtle into Wartortle. Otherwise you'll have to trade with someone who picked Squirtle as starter.
You can only obtain squirtle as your starter pokemon( your first pokemon) or through trade.
yes near vermillion city there is a camper near a lass or camper girl he has a squirtle.
you have to migrate from leafgreen/firered from squirtle
only if you had a gameshark or if it was your starter
