A house in Cianwood has a guy who give you a Secretpotion. Use it on ampharos.
You can't catch Amphy. Amphy is owned by Jasmine.
Amphy, the sick Pokémon at the top of the Olivine Lighthouse you must cure with the Secretpotion, is an Ampharos.
You can not catch amphy
secret potion which you get by surfing to cianwood starting from the beach in olivine
It is in Olivine City. You'll need to cure Amphy that is in the Lighthouse. (That's what Jasmine call the Amphoros.) Then she'll be in her Gym.
Go west of blackthorn city and in your party have the following Pokemon - Gyarados , Nidoking , dragonite and todile and capture it with a heavy ball
You do not get to remove Amphy from the Lighthouse. Training a Mareep to get an Ampharos should be simple enough.
if you mean jasmine's amphy then you cant. however, if you evolve mareep into flaffy, then evolve it again, you can get one. hope this helps!
Just evolve a mareep
You use oran berries.
Super potions can be bought at any local mart. However, you may be referring to the secretpotion needed to cure Amphy the ampharos. To get it, first talk to Jasmine at the lighthouse. She'll tell you to go to the Cianwood City Pharmacy, which will give you the secretpotion for free to cure Amphy.
first you have to guse surf to go to a city and there is a phamacy there
