What generation and game are you using? Of the list you said I'm pretty sure I can get you Caterpie, Pidgey, maybe a Pikachu (just need to check, not sure of the top of my head), both Nidorans Ninetails (I can get you a vulpix whihc you could evolve) Bellsprout and Geodude and a Poliwag (which becomes Poliwhirl).
