Blue Egg

"We're the Eggs! Kazooie can learn to use us as ammo!"

- A Blue Egg, Banjo-Kazooie

Blue Eggs are used as the sole projectile weapon in Banjo-Kazooie, and are 1 of 5 types of projectile eggs in Banjo-Tooie. Kazooie can shoot them out of her mouth or her backside. She can hold a maximum of 100, or 200 if a cheat code from Cheato is used. The blue eggs are an important factor in the games such as filling a Blue Egg Toll or defeating Gruntilda.

In Banjo-Kazooie, a larger variant called the Giant Blue Egg appears in the final room of Gruntilda's Lair right before fighting Gruntilda herself. By collecting the egg, Banjo and Kazooie's supply of Blue Eggs are refilled entirely.

In Banjo-Tooie, the eggs come in nests and Kazooie can fire up to three eggs at a time. They are the weakest type of eggs Kazooie can use, but can be held in higher capacities than any other egg type. Considering that they talk, they may be enemies of Gruntilda because they allow Kazooie to shoot them and destroy them.

Trivia

 * According to Juju and Croctus, blue eggs are quite tasty.
 * In Banjo Tooie, blue eggs are unnecessary if Dragon Kazooie is toggled on, since Fire Eggs are in infinite supply and deal more damage than normal ones. However, one Blue Egg is still required to activate the Pot o' Gold in Cloud Cuckooland.
