How do you become a good trainer to get Bulbasaur in Pokemon Yellow?

what you do is when they give you the mytery dungen test it willl ask you questions and which ever Pokemon you are like they chose randomly you can be

bulbasaur, charmander, skittty ,pichachu meouth and i for get the rest lol.....

PS: if you don't like the Pokemon you are turn it off and restart

Replyyou can also recruit all of the starters in the joyous tower after you beat the game. (your team will enter at level one)
