Rigged Squirtle created in a more „realistic“ style. Squirtle is a small, light-blue turtle Pokémon with large eyes, a curled tail, and a protective shell that hardens after birth. It walks on two legs but can run on all fours. Its shell aids both defense and swimming, letting it move quickly in water. Squirtle can spray water with precision and is usually found near ponds, lakes, rivers, or islands, though it is rare in the wild. It withdraws into its shell to sleep safely, with several noted sleeping styles. Sharpedo is its natural predator. In Generation II, Squirtle and its evolutions were the only Pokémon to naturally learn Skull Bash. Squirtle evolves into Wartortle, which evolves into Blastoise.
