Bulbasaur is a small, quadruped Pokemon with green to bluish-green skin and darker green patches. It has red eyes with white pupils and sclera and pointed, ear-like structure on top of its head. Its snout is short and blunt, and it has a wide mouth. A pair of small, pointed teeth visible in the upper jaw when its mouth is open. Each of its thick legs ends with three sharp claws. On its back is a green plant bulb, which is grown from a seed planted there at birth. The bulb provides it with energy through photosynthesis as well as from the nutrient-rich seeds contained within.
