rattata is small and very quick, and is a common sight in many places. This pink-ish rodent creature will bite anything in its path. In “Bulbasaur and the Hidden Village,” Ash and co. see two adorable Rattata frolicking about in the fields as our heroes enter the village. They then realize that the village is a great Pokémon sanctuary, where sick and abandoned Pokémon can recover and grow.
