Moomoo Farm, Routes 38-39, Glitter Lighthouse, Routes 40-41, Cianwood City, Cianwood Gym (#017)

Joshua & Fjelstan head west. They bop to great tunes on their PokéGear on Routes 38 & 39, visit the Miltank cult at Moomoo Farm, and investigate the Glitter Lighthouse in Olivine City. Its Gym Leader, Jasmine, won't fight them until the Ampharos is cured. In a quest for rare medicine, they head south through the inaccessible Whirl Islands, and arrive in Cianwood City, where they get the potion and then "Chuck" the Gym Leader into the sea.
