Squirtle is a Water-type Pokemon introduced in Generation 1.
It evolves into Wartortle at level 16, which evolves into Blastoise starting at level 36. Along with Charmander and Bulbasaur, Squirtle is one of the three starter Pokemon of Kanto available at the beginning of Pokemon Red, Green, Blue, FireRed, and LeafGreen.
Squirtle's shell is a useful tool. It can withdraw into the shell for protection or to sleep. The grooved, rounded shape helps to reduce water resistance when this Pokémon swims. Squirtle can spray foamy water from its mouth with great accuracy. Squirtle is scarce in the wild, although it can be found around small ponds and lakes.
1) Squirtle is a combination of squirt (to spray and small child) and turtle.
2) As a species, Squirtle has been trained most frequently of all the Kanto starter Pokemon by major anime Trainers, with Ash, May, Gary, and Tiemo each owning one.
3) The Squirtle Squad is a group of Squirtle who were abandoned by their Trainers. They are easily identifiable by the fact that they all wear sunglasses.
