Squirtle

Squirtle is a Water-type starter Pokémon. In the anime, both Ash Ketchum and May each own a Squirtle. Ash's Squirtle was a leader of the Squirtle Squad and May's Squirtle was given to her from Professor Oak. Tierno had a Squirtle that was given to him from Professor Sycamore. It soon evolved into Wartortle and then into a Blastoise.
