Rupee Good

Rupee goods are items in Freshly-Picked Tingle's Rosy Rupeeland that are collected by doing various tasks and quests. They are stored in Tingle's House on the second floor.

If you collect all of them, you can free Pinkle from Uncle Rupee. When you do, Pinkle will give Tingle a "very special reward" and provide him with aid during the final battle.
