Ivysaur is a dual-type Grass/Poison Pokémon. It evolves from Bulbasaur starting at level 16 and evolves into Venusaur starting at level 32.
Ivysaur, like its pre-evolved form, Bulbasaur, resembles a toad or a quadruped dinosaur, though the patches in its skin cause it to resemble a dinosaur more closely. After evolving from Bulbasaur, Ivysaur grows small fangs and has visible ear insides and pupils. Ivysaur’s skin is also a little bit bluer than Bulbasaur’s. The most notable difference in Ivysaur’s appearance, however, is that its bulb has changed into a pink flower bud with leaves extending. This flower bud is heavy, thus making its back legs grow strong and sturdy to support it, causing it to be unable to rise on its hind legs. In Sugimori artworks and game sprites, Ivysaur’s eyes are red. In the anime, Dream World, and Pokémon Trozei!, its eyes are purple. Again, it has three toes or claws growing out of its legs.(Read more on Bulbapedia)

It looks like a green Brachiosaurus dinosaur with a pink and white flower around its neck. It has two long antennae on top of its head.
