If you find the Abandoned ship east of Slateport City, find the Scanner and return it to Captain Stern, he will let you choose either the deepseatooth or deepseascale which will evolve Clamperl into either Huntail or Gorebyss when it is held and traded, respectively.
You can't find one, you have to Trade A clamperl and make it hold a DeepSeaTooth
i think you get it from steven.If now then sorry i dont know. :( <-----That's not right. You have to get the scanner first in the abandoned ship and you trade it to Captain Stern for a deepseascale or a deepseatooth.
Depends on what you want your clamperl to be, Deepseatooth=Hauntail Deepseascale=Gorbyss (or howeverit's spelt)
Trade it holding the DeepSeaTooth or the DeepSeaScale. DeepSeaTooth will give you Huntail, DeepSeaScale will give you Gorebyss.
clamperl
It is a hold item for Clamperl and if you trade it while holding the deepseatooth it evolves into something, but the other person gets its evolved form
I find scanner in Abandoned ship. By the way, to get it you need pokemon that can Surf and Dive. After get scanner, head to Slateport City and go to the Harbor. Give it to him, and he'll give you DeepSeaTooth or DeepSeaScale. You may only choose one. If you trade Clamperl while holding DeepSeaTooth or DeepSeaScale, Clamperl will evolve.
for huntail,you have to trade clamperl holding a deepseatooth for gorebyss, you have to trade clamperl holding a deepseascale
FIrst you must get a scanner. Then you give it to a guy in the slateport port. He will let you choose between deepseatooth and deepseascale.
you trade it with a deepseatooth or deepseascale
Clamperl when traded
If you want a Huntail, get a DeepSeaTooth. If you want a Gorebyss, get a DeepSeaScale. To evolve Clamperl, trade it while it's holding one of those items.
