Double Power
Double Powers, also known as Power 2, are power-ups in the original Rayman game, Rayman Junior and Rayman Designer, looking like small red balls with the letter P, around which gravitate two health points. They restore Rayman's health by two points.
A Double Power gives you two energy points.—Manual, Rayman
There are similar pickups called Simple Powers, which restore Rayman's health by only one point, and another type called a Big Power, which restores his health completely.
