HP Drain P is a badge in Paper Mario: The Thousand-Year Door. This badge can be equipped by using one BP. While equipped, every turn, Mario's active partner will restore a single point of HP. This badge lowers the attack of Mario's partners by one. Near the end of Chapter 6, Mario goes to Poshley Heights and inside of Goldbob's house is this badge. In a secret area accessed via a thin hole in the wall, this badge is found in a treasure chest.
