The Boo's Sheet would replace the Repel Gel in Paper Mario: The Thousand-Year Door. When it is used, it will be able to make Mario or his partner invisible for a total of two turns. If an enemy tries to attack them, they will miss. It can be purchased on the [[Excess Express] for twenty coins, purchased from Charlieton for eighteen coins or made from a Repel Cape and Point Swap. It can also be stolen by the Hyper Goombas, Hyper Paragoombas, and the Hyper Spiky Goombas.
