Early on in your quest through the remake of the classic Gamecube RPG Paper Mario: The Thousand-Year Door, you'll run into a Toad in Rogueport named Zess T. After being run into by a random thief, she will drop her contact lens, which Mario will unfortunately walk on and squish into oblivion. In order to get to the west side of the city, you'll have to get her a replacement contact lens.
