Ford Cruller runs a shop located in the Lodge in the Main Campground where you can buy things to help you along your journey. Each item has a cost, and a rank. You'll need to have the amount of arrowheads listed and also be at least the Rank listed if you want to purchase the item.
When in the shop, use 'Y' to buy, 'X' for info on an item (or read the descriptions below), and 'B' to exit.
My advice would be to save up for the Dowsing Rod first, then buy the Cobweb Duster; the sooner you have it the less backtracking you'll have to do for missed cobwebs. Lastly, save up for the Mental Magnet. Of course, buy PSI-Cores whenever you have enough cards to complete one. The rest is up to you if you want it or not.
Here are the things you can buy and what they do:
| Item | Cost | Rank |
|---|---|---|
| Cobweb Duster | 800 | 20 |
| PSI Energy Colorizer | 250 | 30 |
| Mental Magnet | 400 | 15 |
| Dowsing Rod | 50 | 10 |
| PSI-Core | 10 | 1 |
| Dream Fluff | 50 | 1 |
The Cobweb Duster allows you to collect the cobwebs you find in people's minds. Cobwebs are a collectible and can be turned in for PSI-Cards.
This is not necessary, but is there for your entertainment. It simply lets you change the color of your Psi-Powers like your shield or levitation ball.
This causes things like Mental Health to be attracted to you in a large radius. They natural will run at you when you find them, but this will basically cause any on screen to come at you instead of just the ones that you are near. Very helpful when you have the money.
This allows you to find arrowheads that are buried deeper than the surface. These are actually always clusters of arrowheads so they help you earn money a lot quicker than the single ones you'll get from the surface and from breaking objects. You'll basically be required to use this to be able to save up enough to buy things like the Cobweb Duster (without spending a ridiculous amount of time.)
These are the item that you will need to complete the broken PSI-Challenge Markers and individual cards you will collect. These are definitly worth purchasing because each one you complete will increase your rank.
You can use these to regain lost health. They'll be stored in your backpack and can be used whenever you need them.
