Tips

Fish with a Super Rod for Luvdisc (40%) and Corsola (15%); Route 128 is one of only two places in Emerald where you can catch Corsola.
Search the route for three hidden Heart Scales, and Dive for a hidden Protein and Pearl.
Triathletes Isaiah and Katelyn both have four PokéNav rematch teams, so register them after you win.
Cooltrainers Ruben and Alexa each pay ¥1632, the highest prizes on the route.
Stock up on Repels and healing items before Diving here, because the Seafloor Cavern is a long dungeon full of Team Aqua.
