Grenade Egg

"For blasting things these eggs were made, don't stand close when you fire a grenade!"

Grenade Eggs are explosive green eggs in Banjo-Tooie. Jamjars teaches Kazooie how to use them from the Pine Grove. Only 25 of these eggs can be carried (unless the "EGGS" cheat is activated, which raises the maximum to 50) and Kazooie must pause in between each firing (as opposed to Blue Eggs, which allow three to be fired in quick succession), but they are one of the most powerful types of eggs (tied only by Clockwork Kazooie Eggs) and arguably the most useful in the game.

Aside from dealing heavy damage to enemies and bosses, not to mention the splash damage which can kill bad guys without a direct hit, Grenade Eggs are useful for destroying rocks and breakable walls, as well as harder enemies like Sput Sput and Fruity. Be careful when using Grenade Eggs as the resulting explosion can damage Banjo and Kazooie if used at close range and can send them flying backwards or even sometimes right off the ledge of a nearby cliff.

In Super Smash Bros. Ultimate, Grenade Eggs appear in the duo's down special, Rear Egg. They bounce slowly along the ground before exploding after a few seconds, and can be picked up and thrown.
