Bulbasaur is a small, quadrupedal amphibian Pokémon that has blue-green skin with darker patches. It has red eyes with white pupils, pointed, ear-like structures on top of its head, and a short, blunt snout with a wide mouth. Small, pointed teeth are visible in the upper jaw when the mouth is open. Each of its thick legs ends with three sharp claws. On Bulbasaur's back is a green plant bulb that conceals two slender, tentacle-like vines, which grow from a seed planted there at birth. The bulb also provides it with energy through photosynthesis and from the nutrient-rich seeds contained within.

Bulbasaur is sometimes seen seen napping in bright sunlight and can survive for days without eating. It is found in grasslands and forests throughout the Kanto region. However, due to its status as a first partner Pokémon, it is hard to come by in the wild and is generally found under the ownership of a Trainer. It has been recently seen living in the Terarium of Blueberry Academy. First partner Pokémon such as Bulbasaur are raised by Pokémon Breeders to be distributed to new Trainers. Having been raised by humans from birth, it is regarded as both a rare and well-behaved Pokémon. It is known to be extremely loyal, even after long-term abandonment. Bulbasaur has demonstrated a nurturing instinct towards younger, weaker Pokémon, such as using its vines to pick up a crying Pokémon and gently rocking it back and forth through the air while singing a "Bulba-by". Its bulb will flash blue when it is ready to evolve, but if it does not want to, it struggles to resist the transformation. Many Bulbasaur gather every year in a hidden garden in Kanto to evolve into Ivysaur in a ceremony led by a Venusaur. Its vines are long and strong enough to allow Bulbasaur to grab the branches of trees and pull itself up to reach Berries. As mentioned in Pokémon Sleep, Bulbasaur sits still and basks in sunny spots during its sleep, possibly trying to absorb nutrients from its seed to grow big.

Evolution

Bulbasaur evolves into Ivysaur, which evolves into Venusaur.
