Koopa Koot's favors

In Paper Mario, the elderly Koopa Koot of Koopa Village will ask Mario many favors throughout the game. Some of the favors require Mario to meet specific people and get an item in return. For every four favors Mario does for him, Koopa Koot will give Mario Star Pieces, making this sidequest a necessity to fully complete the game.
