You can't catch a Squirtle. It's one of the Pokemon you can get from oak. You have to trade with someone who already has a Squirtle.
you cant catch venusaur in Pokemon blue you pick at the start of the game out of charmander bulbesaur and squirtle if you want venusaur you pick bulbesaur
No.
the answer is no
No.
You can't. Squirtle is a starter Pokemon, you have to trade it into your game.
Squirtle is not available in Pokemon Crystal. Squirtle can only be found in Pokemon Red, Blue, or Yellow. Squirtle can be traded to Crystal from those titles.
Squirtle
you can't, you need to trade with a game that you can start with a squirtle (ie. Pokemon leafgreen, Pokemon firered)
you have to get it on any GBA Pokemon games
You cant catch a squirtle in Pokemon firered nor in Pokemon leafgreen. Squirtle is a starter Pokemon so you cant find or catch one unless you use a game shark.EDIT by Man spider27: Although it is- as far as I know- impossible to capture Squirtle or Bulbasaur in Pokemon leafgreen it is possible to find Charmander in the Old Mansion on Cinnabar island. Hope I helped!
They are not catchable on any Pokemon game,however you can trade to get the starter Pokemon squirtle and charmander on Pokemon Leafgreen/Firered.
