if you mean the medicine for 'amphy' in the light house, go to the medicine man in cianwood city he will give you a 'secret potion'
You catch a Marrep then evolve it at level 15 to Flaafy then at level 30 it will evolve into Amphy
You do not get to remove Amphy from the Lighthouse. Training a Mareep to get an Ampharos should be simple enough.
Cynthia will give it to you.
go to the left of moo moo milk shop, then give the secret potion to the psyduck :)
if you mean the medicine for 'amphy' in the light house, go to the medicine man in cianwood city he will give you a 'secret potion'
If you mean super potion, buy it at the store. If you mean SpecialPotion to heal Amphy, Cianwood city across the ocean.
When amphy the ampharos is sick, she'll be at the top of the lighthouse in Olivine City. Surf to Cianwood City and get the Secretpotion from the pharmacy. Then beat the gym there and you'll obtain Hm fly, Fly back to olivine and go to the top of the lighthouse to give the potion to amphy.
you need a hm 'surf'. swim southwest from that city <darn,i forgot it!!> where you have seen that sick amphy and you'll reach the land where there are gym leader Chuck. go to the last house near water in southeast of the island and go to that house. there will be a man and talk to him. he'll give u a secret potion. and you'll have to give it to amphy.
secret potion which you get by surfing to cianwood starting from the beach in olivine
I don't know its name pretty sure it is either rare or secret potion talk to a man in cianwood pharmacy (he looks like the guy that cheers you on in the gyms) and he will give you it go back and give it to amphy and the gym leader tada good luck trainer
you go to ciantown and go to the house next to the Pokemon cebter that says pharmacy and talk to the man so he will give you a hyper potion....................by the way i luv cats = ^ . ^ = ~meow~
Can't get amphy
You can't catch Amphy. Amphy is owned by Jasmine.
You give the potion to whom?
When u are in olivine city u can't battle the gym leader, jasmine, until u bring a potion to the sick pokemon, amphy. U have to surf to cianwood city where you have to go to cianwood city pharmact where the man will give you a potion. U then have to surf back to olivine city's lighthouse where you will finf jasmine, the gym leader, right on top with the sick pokemon. Hope I've helped!!
You can not catch amphy
