Clockwork Kazooie Eggs are a variety of eggs found in Banjo-Tooie.
Drill Sergeant Jamjars will teach Kazooie how to use these in the Wasteland of the Isle O' Hags. In a sense, they are advanced Grenade Eggs. However, rather than just shooting them at targets, Clockwork Kazooie Eggs will hatch small, controllable, mechanized Kazooies known as Clockwork Kazooies. Clockwork Kazooies are fairly useful, as they can fit into places that are either too narrow or out of reach for Banjo or Kazooie. Clockwork Kazooies only last for a limited time before blowing up, although the player can detonate them prematurely if needed. Clockwork Kazooies can also be used to pick up items, particuarly any ones in the areas that Banjo or Kazooie cannot reach. Banjo and Kazooie can only hold 10 of the large Clockwork Kazooie Eggs, although a Cheato spell can double their capacity to twenty.
