Bulbasaur is a GrassPoison-type Pokémon introduced in Generation I. It is one of the three starter Pokémon of Kanto along with Squirtle and Charmander. Bulbasaur is also known as the 'Seed Pokémon'. It is the easiest to raise because it turns into Venusaur at Level 32, rather than Level 36 that the other Kanto starters fully evolve.
Bulbasaur can be received from Professor Oak as a your Starter Pokémon or by purchasing the 'Kanto Starters' gamepass. Owning it will enable a 1/7 chance to find Bulbasaur at Route 1. You can also obtain Bulbasaur by trading or at the pokemon roulette.
