Lordly Hairpiece
Defeating the "Patapon 2" demo provides the chance to unlock a most unusual item. Once you've defeated the demo, save the achievement and upload the save in "Patapon 2." Doing so will unlock the Lordly Hairpiece, a powerful toupee that grants full status protection to its wearer.
Random Item
If you have a saved file from the original "Patapon" game with items in your inventory, load it into "Patapon 2," and then travel to Tochira Beach when it's raining. There should be a treasure chest on the beach. Bust open the chest to find an armor piece or a weapon from your original "Patapon" inventory.
Easy Bones
Don't play the Angry Monster Bird Motititi mission until you reach Level 5 and upgrade your Patapons to Menyokki status. Arm your Patapons with weapons that can put the monster to sleep without inflicting serious damage. If you can prolong the monster's life by putting it to sleep, you'll receive more bones for little to no effort.
