The Weapons Shop

To battle the evil pigs, you need a good weapon. When you start your adventure, you've got a Blackjack. The Blackjack is okay, but keep your eyes open when out and about. You're sure to find faster and more powerful weapons.

When you do find a new weapon, you have to equip it to use it. Just hit triangle to get to the Item Screen, pick the weapon you want, then hit Use Item. It's that easy to equip a new weapon, but you also got to know how to use it.

Blackjack
Again, the Blackjack is your standard weapon. It's okay, but you won't be able to finish your quest with it. It'll get you started though.
Grapple
Oh, now here's a nice piece of weaponry. Shoot this into a wall or ceiling, and it'll latch on. If you're hanging onto it, you can climb up and down. It's great for getting to those hard-to-reach places.
Wood Boomerang
The Wood Boomerang can do some pretty healthy damage. It's got better range than the Blackjack and can really knock the oink out of those pigs.
Stone Boomerang
Time for the heavy artillery! The stone boomerang not only has more range and power than a wood boomerang, but you can fire two at a time! Now that rocks!
