HP Plus P is a badge found in Paper Mario: The Thousand-Year Door. This badge enables each of Mario's partners to have his or her max HP increased by 5, but at a cost of 6 BP. As is the case with most badges, it is stackable.
This badge can be obtained in several ways:
- Mario uses Yoshi to reach a box located on the second floor of the Secret Room in Glitzville.
- Mario can find another one by reaching the end of the road that leads to Fahr Outpost. Enemies can occasionally be found with the badge, and Ms. Mowz is needed to steal it from them.
- Mario can purchase the badge for 200 Pianta Tokens at the Pianta Parlor.
