In the last kanto leader geovanni. You get it no lower than level 29
no, in Pokemon yellow though, you get at route 17 or 18 by using a super rod. Its level is 25. pokemonyellowman245
Out of curiousity I surfed directly behind Valley Windworks in Pokemon Diamond and used a super rod and found a Shellder on my first try.
in route 201
at route 999
Lilycove city
Phanpy can be found at Route 120.
Shellder appears in the bodies of water in the lower part of Route 205, the Valley Windworks, and Fuego Ironworks. You need a Super Rod to catch one.
You can find Shellder commonly in Route 21, Vermilion City, Cinnabar Island, Olivine City, and Seafoam Islands. You will need to fish in the bodies of water to encounter it in the wild.
Did you mean sheildon, shelgon, or shellder? Shieldon: Pearl only. Shelgon: Evolve Bagon. Bagon is Pearl only Shellder: Route 205; use super rod.
Machop can be found in Lilycove City.
that game doesn't exist anymore the new game is Pokemon indigo just Google it.
There is no route 23 in Pokemon gold but if you mean heart gold it is the north exit of indigo plateau south exit of route 22 and west exit of victory road.
Sorry to say, but you can't catch Cloyster. You have to catch a Shellder with a Water Stone. You can catch a Shellder by fishing in Olivine City (SS Aqua Entrance), Vermillion City, Cinnabar Island, Seafoam Island and on Route 21.
Fish with the Good Rod or Super Rod at New Bark Town, Union Cave Route 26, Route 27, Olivine City, Vermilion City, or Pallet Town.
