Ivysaur

Ivysaur (Japanese: フシギソウ Fushigisou) is a dual-type Grass/Poison Pokémon introduced in Generation I.

Physiology
Ivysaur's appearance is very similar to that of its pre-evolved form, Bulbasaur. It still retains the turquoise skin and spots, along with its red eyes. Ivysaur's top fangs are now larger and are visible outside of the mouth. Also, its ears are now darkened to black in the center. The most notable change is that the bulb is starting to bloom, with pink petals visible, and large leaves on the bottom.

Abilities
Ivysaur's ability is Overgrow, which increases the power of Grass-type attacks by 50% once the Pokémon has less than one-third of its maximum HP.

The bud that it carried on its back as a Bulbasaur has grown into a full blossom when it had evolved and can grow larger in sunlight. As the blossom grows, Ivysaur loses the ability to stand on its hind legs. The blossom produces a pleasant smell when it is ready to bloom, and Ivysaur is ready to evolve into Venusaur.

Evolution
Ivysaur will evolve from Bulbasaur at level 16 and evolves into Venusaur starting at level 32.
