Extra Honeycomb Pieces (also referred to as Hollow Honeycombs) are collectibles found in Banjo-Kazooie, Banjo-Tooie, and Banjo-Kazooie: Grunty's Revenge. Usually hidden in hard-to-reach places throughout the games' worlds, collecting a certain amount will increase Banjo and Kazooie's maximum energy capacity by one honeycomb.
