you get there by capturing snorlax
there is no diglet cave.
diglet is in diglets cave
Nothing you could just find the Dugtrio or Diglett
Outside of diglets cave
Ummm..... Diglett`s cave is not a secret, anyone who actually has played pokemon would know that...... And no you do not get torchic there.
there is none. fire red and leaf green has one.
in frunt of diglets cave use the poke flute (it is on your radio)
go to raido tower and get the poke flute
you will go to route 2 peter city side
go through diglets cave in vermillion city
Other Pokemon do know dig without the TM dig. Most DIGlets know dig. Find diglets in Diglet cave. Hope this helps!
You have to go to diglets cave and get to the end. Make sure one of your Pokemon knows cut.
