Giant Step

With Franky taken care of, it's now time to visit your first sanctuary. The shack north of town that is locked can be accessed by getting the key from the Mayor.

Once you have the key, make sure you stock up on some burgers since there can be some pretty tough battles ahead depending on your level.

Also, after you unlock the door, talk to the guys hanging out next to the shack again and one of them will give you a Travel Charm that you can equip.

As you make your way through the caves, you will encounter a number of enemies. The Attack Slugs are the easiest and will make it easy to get more experience points. 

The Black Antoids will call others to help so make sure to knock those out first.

There are also a couple of presents along the way. Nothing too impressive but who doesn't like opening presents? Refer to the map for locations.

Halfway through the cave you come to an area that has a Magic Butterfly. Use PSI Lifeup before you use the butterfly and you'll be back at 100% heading in to the big battle.

If you want to make it through this battle easily try to reach level 12 or 13.

Try not to let any of the Black Antoids live or they will keep calling for help. Use your PSI attack until your PP is gone because he likes to drain your PP. So don't try to conserve PP!

After you've used all your PP just bash and keep your HP up with foods.

You got this!

Exit the cave and you will find a stinky foot print in the grass. Walk up to it and you'll hear the first melody for the Sound Stone.

On the way back out of the cave you'll notice that the enemies are now terrified of you. This can be a great time to level up if you want.

Once you've made it back to the shack, one of Onett's finest will demand you go to the police station.
