Red Jar

The Red Jar is a special item from Paper Mario. It can be obtained through doing one of Koopa Koot's favors.

Koopa Koot's final favor in the game is to get a Red Jar, which are said to be made in the Dry Dry Outpost. To get the jar, Mario has to go to Little Mouser's shop and by a Dusty Hammer, a Dried Pasta, another Dusty Hammer, and a Dried Shroom, in that exact order. Upon doing so, Little Mouser claims that buying those items in that order is part of an ancient will, and his part in fulfilling the will is giving Mario the Red Jar. However, upon giving the Red Jar to Koopa Koot, he is disappointed with it, claiming it is filthy, though he decides to keep it anyway. Doing this last favor will earn Mario 3 Star Pieces.
