"It’s rear head also has a brain, but it is small. The rear head attacks in response to smells and sounds. Approaching this Pokémon from behind can cause the rear head to suddenly lash out and bite."
Yes, you read that Pokedex entry right, Girafarig has two heads, and two brains, and that's freaking scary. This Johto Pokemon again takes the base of a real world animal and adds some Pokemon flair to it in a grand (and scary way), add this to the fact that it's a psychic type Pokemon, and this isn't something you underestimate.
Giragarig's Basic Attacks are Tackle and Confusion while its Special Attacks are Psychic, Thunderbolt and Mirror Coat.
