when u get an Shellder. the only way to evolve it is using a water stone! sadly, i used my water stone on my eevee a long time ago! (i am mad at myself)
fishing is a good way to find one. check for its area locations in the pokedex, then go fishing there. if u don't have it in, go fishing around the docks or vermilion city, that's where i found some.
Super Rod.
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.
You can catch shellder in the museum at Oreburgh city,,, to catch it you must go through a secret passageway in the back and you ill find a secret garden with shellder's and eevee's. It don't work wheres the secert passageway.!!!.!!!?!!! There is no such thing. You get a shielder on route 205 with a super rod, and eevee are found in the Trophy Garden or in front of the mansion.
No, you have to trade it from FireRed or Pokémon XD: Gale of Darkness
You can find shellder at rout 26.I'm pretty sure your going to need a super rod so if you don't have one you can get it from this one fisher dude somewhere between routs 15 and 14. I'm pretty sure that shellder comes out at any time of the day but if that's not true then it for sure 100% comes out at night :)
You could catch a Shellder at Valley Windworks only by using your super rod
