Olivine City, far right
You need to go to Cianwood Pharmacy and get the Secretpotion.
You get it at the Cianwood City Pharmacy. It is used to Cure The Lighthouse Pokemon Ampharos. This answer is right-on. the pharmacy in Cianwood City in the Johto Region, and it is used to cure the ailling lighthouse Pokemon ampharos.
On the top floor of the lighthouse, oilvine city, Johto region. Hope I helped!
You find it in the Glitter Lighthouse in Olivine, or in the Celadon Dept. Store.
she is at the top of the lighthouse but its hard to get to the top. When you get to the highest floor you can get to go out the window on the right. You will be outside on the side of the lighthouse. go forward and then left. There is a door. go in and keep going up in the lighthouse. Hope it helps!!
lighthouse, watching "Amphy"
yes huey he is in the lighthouse
No. When you walk into the phrmacy in Cianwood City, (an average building towards the bottom of the town) and talk the the single man inside it, he will automatically give you the potion to revive it if you have talked to jasmine in the lighthouse already.
if you are meaning the medicine for ampharos the sick Pokemon from the lighthouse then it is at cianwood city... there is a place where you can get special medicine for ampharos (the sick lighthouse Pokemon) then take it back to the female (which is the gym leader for olivine.) that is looking after him. then she goes off and you can go battle her in her gym in olivne..! I hope I've helped ~Amelia age 6~
