Dratini

Dratini is a serpentine Pokémon with a blue body and a white belly. It has a white fin on either side of its head and a white bump on its forehead. Above its large, round, white snout are oval, purple eyes. As Dratini is filled with life energy, it is constantly growing, and can thus grow to be over six feet long. As it grows, it sheds its skin. Whenever Dratini undergoes shedding, it hides behind a large waterfall. It has been found in colonies living underwater.
