BK Emptyhoneycomb

One of the many Empty Honeycombs in Banjo-Kazooie.

Empty Honeycombs, sometimes referred to as Extra Honeycomb Pieces, are large, hollow honeycombs found in the Banjo-Kazooie series. Although Empty Honeycombs provide no immediate reward, once enough are accumulated, they can be exchanged for additional units of honeycomb energy.

In Banjo-Kazooie, there were six Empty Honeycombs in Spiral Mountain, plus an additional two in each of the game's nine levels, for a total of twenty-four. For every six pieces that Banjo and Kazooie collected, their honeycomb bar increased by one unit. The duo, which started the game with an initial five units of energy, could earn up to eight units. As such, only eighteen of the game's twenty-four Empty Honeycombs were needed, as collecting the remaining six gave no reward of any sort.

In Banjo-Tooie, the Empty Honeycomb system was altered. Banjo and Kazooie had to bring their collected Empty Honeycombs to Honey B. and exchange them for additional units. Instead of trading in six Empty Honeycombs for each unit every time, Honey B. required only one for the first exchange, and increased the cost by two every time, up until nine, utilizing all twenty-five Empty Honeycombs in the game. In the end, Banjo and Kazooie could have up to ten units of energy.
