what do you mean by earth ground or grass Pokemon
in the earth
nidoking and nidoqueen
Pokemon
There is NOT any guards in Pokemon in the middle of the earth.
there isn't an item called earth stone in ruby.......
It never learns earth power unless you trade it to a 4th generation Pokemon game.
I'm guessing 'Earth type' is 'Ground' types?. If it is, Water types, Grass types and Ice types. So try too get these Pokemon: Samurott, Vileplume, and Weavile.
In the movies it says that all Pokemon came to Earth on a colossal meteor from space.
Get a earth stone
you can't. earth power is unobtainable as a tm.
Go to Indigo Plateau, battle the Elite Four and the Pokemon Champion.
cant get it as a tm, but you could catch it from one of the wild pokemon
