1.
A grass type pokemon. Evolves into Ivysaur, and then Venusaur. Attacks include Leech Seed, Vine Whip, Razor Leaf, and Solar Beam. Walks on all fours, and has a blub on its back. Weak against fire and flying pokemon.

"Dude, I caught a BULBASAUR over by that guys house, you wanna meet him it my room later?"

"I'm getting sick of catching BULBASAUR, we need to evolve to an IVYSAUR, and if we can get a VENUSAUR, I'll totally shit a brick!"

"Man, I was chillin' with my BULBASAUR all weekend..."
