Confetti Bag

The Confetti Bag is an item in Paper Mario: The Origami King. Mario uses it to store confetti. Olivia gives Mario the Empty Confetti Bag after both of them are stuck on opposite sides of a Not-Bottomless Hole in Whispering Woods. The Confetti Bag can then be filled up and used to fill the hole. After Mario destroys a streamer, the Confetti Bag is able to hold more confetti.
