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

It evolves from Bulbasaur starting at level 16 and evolves into Venusaur starting at level 32.

Ivysaur is a quadrupedal Pokémon that has blue-green skin with darker patches. On top of its head are pointed ears with black insides and it has narrow red eyes. Ivysaur has a short, rounded snout with a wide mouth and two pointed teeth in its upper jaw. Each of its feet has three claws on them. The bulb on its back has bloomed into a large pink bud. A short brown trunk surrounded by leafy green fronds supports the bud.

The weight of the plant prevents Ivysaur from running fast and standing on its hind legs and forces its legs to grow sturdy. When its flower is ready to bloom, it gives off a distinct, strong sweet-smelling aroma and starts swelling. Ivysaur will also start spending more time in sunlight in preparation for its upcoming evolution. Exposure to sunlight adds to the strength of both Ivysaur and its plant. Ivysaur’s natural habitat is plains.
