Biology
Squirtle is a small, bipedal Pokémon with a thick shell. While it typically walks on its two short legs, it has been known to run on all fours to go faster. It has large, eyes and a slightly hooked upper lip. Each of its hands and feet have three pointed digits. The end of its long tail curls inward. Its body is encased by a tough shell that forms and hardens after birth. This shell is brown on the top, pale yellow on the bottom, and has a thick white ridge between the two halves.

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, allowing the Pokémon to swim at high speeds. 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, though they've also been found living on secluded islands with other members of its evolutionary line.
