This little reptil/plant/dinosaur-like creature has a large bulb that grows on its back. The bulb and saur are actually separate entities that work together in a sort of symbiotic relationship. The Bulbasaur gets enhanced energy from the sun and many attacks to draw from, while the bulb gets… um, I don’t know, a place to sit. Interesting little fellow anyway.
“Bulbasaur Anatomy” peels back the cartoon layers of Pokemon science and discovery. I would give you more specifics, but unfortunately, I don’t read Japanese.
