Big Power
Big Powers, also known as Super Powers, are power-ups in the original Rayman game, Rayman Junior and Rayman Designer, looking like red balls with the white letter P on them. They restore Rayman's full health, and increase his maximum life points to 5. If Rayman loses a life, this effect will be cancelled.
A Big Power gives you a full load of 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 Double Power, which restores his health by by two points.
