Hollow Honeycomb

"I'm an Extra Honeycomb Piece! Collect six of us to increase your energy bar!"

- Extra Honeycomb Piece

Hollow Honeycombs, originally known as Empty Honeycombs , Extra Honeycomb Pieces , or Honeycomb Pieces , are recurring collectible items in the Banjo-Kazooie series. Banjo and Kazooie can collect a certain number of them to add a honeycomb to their health bar. Hollow Honeycombs are often found in out-of-reach areas.

Banjo-Kazooie
In Banjo-Kazooie, every six Extra Honeycomb Pieces add another honeycomb unit to Banjo and Kazooie's health bar, which can have up to three units added, making for a total of eight units. Oddly, the remaining six Extra Honeycomb Pieces do not add a ninth unit to the health bar, despite still playing the sound effect and showing the animation for whenever Banjo collects and Extra Honeycomb Piece.

There are six Extra Honeycomb Pieces in Spiral Mountain plus two in each of the game's nine levels, making for a total of 24 Extra Honeycombs. Two Extra Honeycomb Pieces only appear upon hitting a Honeycomb Switch, one of them in Gobi's Valley and the other in Rusty Bucket Bay.

In the Xbox Live Arcade version, collecting all 24 Extra Honeycomb Pieces unlocks the "Show me the Honey!" Achievement. Their speech icon is larger than in the original Nintendo 64 release, although an unused variant based on the original speech icon exists in the game's files.

Banjo-Tooie
In Banjo-Tooie, they are renamed to Empty Honeycombs, and there are 25 of them to collect. The system for collecting Empty Honeycomb was altered, so to receive extra units for their health bar, Banjo and Kazooie must trade their Empty Honeycombs to Honey B. Her first exchange required only one Empty Honeycomb, but every subsequent exchange increases the cost by two Empty Honeycombs. The fifth and final exchange with Honey B. requires nine Empty Honeycombs, allowing Banjo and Kazooie to have ten units for their health bar. There are three Empty Honeycombs in every level.

Banjo-Kazooie: Grunty's Revenge
In Banjo-Kazooie: Grunty's Revenge, they were renamed again to Hollow Honeycombs. Their role is very similar to Banjo-Tooie, as Banjo must trade them to Honey B. at her hive to have extra units added to his health bar. There are four separate exchanges, the first requiring two Hollow Honeycombs, and the following three requiring four, eight, and twelve Hollow Honeycombs respectively.
