Map of Onett
Hidden Club House
One of the most fun little secrets in Onett is the club house hidden in the trees just as you enter the outskirts of town.
Just walk into the opening between the trees and head north and you'll enter the elusive tree house where you can obtain the Mr. Baseball cap. Definitely a nice little piece of equip to pick up early in the game.
Now is a great time to walk around and talk to the townsfolk. You can go into most homes and learn a lot. Some people have their doors locked and will yell at you from their couch. Also, your character loves digging through trash cans, so definitely do that.
Just be careful around the Video Game Arcade. The Onett Sharks hang out there! When you're ready to start leveling up you can battle them.
If you've fought enough enemies you can withdraw from the ATM and buy some equipment at the Drug Store.
After you've got some new equipment and stocked up on some Hamburgers you'll want to fight the Onett Sharks near the Arcade until you reach Level 8 where you learn your first PSI attack skill. This will make the battle much easier. Otherwise, if you want a challenge, go straight to Franky without trying to level up.
Right before the battle with Franky you have to fight one of the Sharks that is blocking the door in the Arcade. Fight him and you'll enter the yard where the throw down will take place.
If you answer "Yes" to his question he'll make a funny quip about finishing the game. If you answer "No" he will call you a snob and try to take you down.
Franky ( Battle )
The minimum level you'll want to fight Franky at is lv6. Just be prepared to heal yourself when your HP gets low since his Knife attack can deal a lot of damage at once.
If you're already at lv8, you should be able to beat Franky with a few Bashes or you can hit him with a PSI attack.
This is a pretty easy battle at lv8, but you struggle more at lower levels.
Frankystein Mark II ( Battle )
Immediately after the battle with Franky you will enter the battle with Frankystein Mark II.
If you have enough PP, hit him with your PSI attack. That should make pretty quick work of him. If you're level is not high enough to use PSI, you'll probably struggle to kill him. Just make sure to keep your HP high and attack him while he's busy doing the generating steam moves.
Onett Sharks Neutralized
After the battle has ended his ego will collapse. He will also give you some important information about your next destination, the Giant Step. He mentions that Officer Pickle has the key that will let you get to the Giant Step.
Now that you've defeated Franky and his machine, the Sharks will no longer attack you. In fact, they have a new found respect for your power. Even Franky will offer his back yard for you to rest in and recoup your HP/PP.
