Proximity Eggs are an item in Banjo-Tooie.
Location and uses
Proximity Eggs are a type of egg used exclusively in the Squawkmatches. When fired from the Breegull Blaster, Proximity Eggs stick to the surface they landed on and explode once they are hit by another egg or someone, either an opponent or a Clockwork Kazooie, gets close. Firing a Proximity Egg at opponents causes them to obtain the egg rather than exploding.
