Pokémon Gold and Silver/Olivine City

'''The port town of Olivine City has a couple of interesting attractions—the Lighthouse and the port for the highspeed watercraft, the S.S. Aqua. There's a problem at the Lighthouse that you need to attend to before you can even attempt to battle the city's Gym Leader.'''

Unused olivine city house
This map is not able to be accessed through normal gameplay. The warp to the house is at the top left part of the map and can only be access through means of cheats. To get to the warp you must have a walk through walls cheat and a cheat that changes the warp behavior. upon walking over the warp with the codes on you will be warped to the unused house which contains two NPC's. one is a Rhydon and the other one is a female NPC. When A is pressed in front of the woman she will say "When my Pokémon got sick, the Pharmacist in Ecruteak made some medicine for me." this suggests that at one point in the game the developers were planning on putting the pharmacist in Ecruteak city.

The Olivine City Gym Leader
When you arrive in Olivine, you'll find your rival lurking near the Gym, but he isn't interested in you. He's looking for Jasmine, the Olivine Gym Leader. The word around town is that she's gone to the Lighthouse to help a sick Pokémon. If you want to win Olivine City's Gym Badge, you'll have to head over to there. The Lighthouse is full of Trainers trying to prove their worth, so be prepared for quite a few battles.

Get the Good Rod
Another generous fisherman, found in the small house next to the Mart, will give you the Good Rod here, so now you can finally catch some decent Water Pokémon. In fact, there are a bunch of good things to fish for right here in Olivine City, and its small harbor.

There are no ships sailing today, but the harbor is still worth a visit for the great fishing opportunities. A, in particular, will be a big help in getting through.

Pick up HM 04 (Strength)
The Sailor in the Café building next to the Poké Center gives you a new Hidden Machine. Teach HM 04 to a Pokémon and not only will it learn a powerful Normal attack, it will also be able to push aside the rounded stones that you see in caves and the upcoming Gym. Pair this with HM02 (Fly), which you acquire soon, you'll be ready to do some item hunting and some backtracking.

Swap a Krabby for a Voltorb
This isn't a particularly exciting trade, since you'll have opportunities to catch wild, but you might as well go for it. After all, you can just step outside this guy's front door, use the Good Rod and fish up an extra right here and now.
