Squirtle is one of the three starters you can choose in the Pokemon games, though not in Pokeslayer 2. You need to kill 40 people with it in order to evolve it into Wartortle. Squirtle is a water type, meaning it is weak to grass types, so if hit by a grass knife, will be dealt 100 damage (death). On the other hand, it is effective against fire, so you will be dealt 40 damage, and deal 100 damage. Some types are neutral against water, and 60 damage can be dealt either way.
