* Bulbasaur is a starter Pokemon in the Kanto region (Generation 1) and Johto region (Generation 2). Pokemon Pearl is part of the Sinnoh region (Generation 4).
* The starter Pokemon in Pokemon Pearl are Turtwig, Chimchar, and Piplup.
Therefore, you cannot get a Bulbasaur in Pokemon Pearl through regular gameplay. You might be able to obtain one through:
* Trading: If someone with a Bulbasaur is willing to trade with you.
* Events: Occasionally, Nintendo may offer events that allow you to obtain Pokemon from other generations.
Hope this helps!
