Ice Egg

"Freezing cold but that's the price...for launching eggs of solid ice!"

- Jamjars

Ice Eggs are a type of egg that Kazooie can use as ammunition. They are used to freeze their targets.

Banjo-Tooie
In Banjo-Tooie, Jamjars teaches Kazooie how to fire Ice Eggs on the Isle O' Hags' Cliff Top if her and Banjo have at least 200 Musical Notes. At first, Kazooie can carry up to 50 Ice Eggs, although a cheat from Cheato doubles it to up to 100.

Kazooie can shoot Ice Eggs at enemies to freeze them temporarily. While an enemy is frozen, Banjo and Kazooie can defeat the enemy entirely by attacking it again, causing it to shatter into pieces along with the ice. Ice Eggs can also freeze Inkys in Atlantis, allowing the duo to safely swim by them. Ice Eggs can directly damage fire enemies such as Hothands, and Chilli Billi during the boss fight against him. Ice Eggs can put out the fire on other enemies caused by Fire Eggs, although the enemy still takes burn damage from the Fire Egg.

Ice Eggs have several uses, especially in Jolly Roger's Lagoon. They can extinguish large fires, such as those in the Bonfire Cavern of Terrydactyland. Ice Eggs can also freeze objects, such as the fans of the water supply pipes in Jolly Roger's Lagoon. Ice Eggs are a power supply for an alien spaceship in the same world.

Banjo-Kazooie: Grunty's Revenge
In Banjo-Kazooie: Grunty's Revenge, Bozzeye teaches Kazooie how to fire Ice Eggs in Spiller's Harbor for 410 Musical Notes. They act mostly the same as they did in Banjo-Tooie, although not as versatile.

Banjo-Pilot
In Banjo-Pilot, Ice Eggs are used a defensive item, similar to Bananas from the Mario Kart series. Like Fire Eggs, they are picked up either individually or in a group of three; these items are respectively called Single Blue Ice Egg and Triple Blue Ice Eggs. When a racer uses an ice egg, it deploys an ice cube that hangs in the air. If an opponent flies into an ice cube, their plane briefly crashes and bounces onto the ground before they get back up. The ice cubes have a one-time use, as when an opponent crashes into one, it breaks apart. This also applies if an ice cube is deployed to protect the user from either a Fire Egg or a Saucer of Peril.
