Ivysaur

Ivysaur, is a dual-type Grass/Poison Pokémon. Ivysaur evolves from Bulbasaur and evolves into Venusaur. The bud on its back apparently draws energy from its body. The bud is said to open into a large flower when fully grown. Ivysaur is stronger and more aggressive than Bulbasaur. The flower bud on its back grows by absorbing nutrients and sunlight, which prepares it for its evolution into Venusaur. Ivysaur prefers sunny areas where it can bask in the sunlight, which helps the flower on its back grow.
