Creature description
Squirtle is a small blue bipedal turtle-like creature. It is also the first stage prevolution of Blastoise, with Wartortle as the evolutionary stage between them. In Pokémon (Red, Green, FireRed, and LeafGreen versions), Squirtle is one of the three starters that the player can choose. It evolves into Wartortle at level 16 onwards and into Blastoise at level 36 onwards.
When it hatches, its shell is soft, and forms and hardens over time until it becomes resilient enough that prodding fingers will bounce off it. The shell is a great protective measure, and the Pokémon withdraws into its shell when in danger. The shell, in addition to protection, also has a rounded shape with grooves on its surface, which helps minimize resistance in water and enables it to swim at high speeds. When threatened, it withdraws into its shell and squirts out water with vigorous force.
Squirtle makes three minor appearances in this game. One of these appearances is a very brief cameo in the opening video.
 As a stage element
A giant balloon of Squirtle (in actuality the 3D model of Squirtle used in Pokémon Stadium for Nintendo 64) is one of the many floating and bending "platforms" that comprise the Poké Floats stage. It is the first balloon in the stage and its head and arms are where the four fighters start off on at the beginning of the match.
 As a trophy
Squirtle features as a collectible trophy, unlocked as one of the 100+ trophies that can be collected randomly during normal play, such as in the Trophy Lottery and throughout the various Single-player Regular Matches. It reads as follows:
 As a playable character
Squirtle appears as a playable character and is one of Pokémon Trainer's three Pokémon, the other two Pokémon being Charizard and Ivysaur. Squirtle can be switched into or out of battle through the down special move by the Pokémon Trainer, which operates similarly to the Zelda-Sheik transformation.
