>>36025791Cyndaquil is solid and there aren't a lot of other great fire type options. Totodile is also good, better in the remakes due to phys/spec split, but is a bit undercut by the presence of some other solid water types. Both would work out just fine.
Chikorita is the hard one to justify. I did a mono-grass run of Johto once and boy did it suck. I caught a Hoppip and Bellsprout fairly early. Leech Seed and Sleep powder on the former made for a way better support mon, and Acid was usually better against whatever I was fighting at most points. That was in Crystal, but basically the only thing Meganium has going for it is dual screens, and you have to wait a long while for Light Screen. Grasa also doesn't help in pretty much any key battles. I think Pryce was actually the easiest since all of this mons are actually weak to grass.
Generally, I like picking Cyndaquil since it's really odd to me for Silver to steal a Chikorita
