Honeycombs are hexagonal sources of energy in the Banjo-Kazooie series. Although honey is favored by bears, namely Banjo, Kazooie, Mumbo Jumbo, or any of the duo's transformations can make use of Honeycombs just as well.
Honeycombs are fairly common throughout the Banjo games, as the player must keep their Honeycomb count above zero in order to stay alive. Most enemies will drop a Honeycomb when defeated. Beehives also contain three Honeycombs which will spill out upon being busted open.
Banjo and Kazooie start each game with a bar of five units of Honeycombs (health), and depending on the impact of any hits they take, they will lose one or more Honeycombs. As Banjo and Kazooie progress throughout their adventures, they will pick up Empty Honeycombs, which they can use to increase their Honeycomb-carrying capacity.
In Banjo-Tooie, the duo will periodically come across Skill Honeycombs and Mystery Honeycombs. Instead of simply restoring one Honeycomb, Skill and Mystery Honeycombs will flash between different levels of health. The player must then use good timing to stop the Honeycomb at a desired level, preferably a higher one. Skill Honeycombs cycle through the bar in order, while Mystery Honeycombs cycle at random.
