|User||Banjo & Kazooie|
Banjo crouches down while Kazooie deploys an explosive Grenade Egg backwards. The egg bounces in a slightly unpredictable fashion before detonating on contact or on a timer. As an item, it can be picked up by any player, though this does not stop it from exploding in characters' hands. However, this property makes the move useful for bomb recovery. Only one Grenade Egg can be present at a time; Kazooie refuses to use another until the first has exploded. If the Grenade Egg gets pocketed, Kazooie cannot produce another Grenade Egg until the opponent who pocketed the Grenade Egg either gets KOed or pulls out the Grenade Egg and lets it explode. Grenade Eggs are fairly versatile projectiles with a variety of different uses, including zoning, camping, approaching, edgeguarding, ledgetrapping and comboing (the latter most of these including KO confirms into forward aerial and Wonderwing), and knowing how to properly utilize them (including picking up Grenade Eggs in midair in order to use them as items) is crucial to playing Banjo & Kazooie.

The manner in which the egg is deployed originates from Banjo-Kazooie, which can be performed after the duo learns how to fire eggs. If the player holds Z and presses the down-C button, Kazooie lays an egg behind Banjo, which bounces away along the ground. Eggs fired this way bounce slowly and with much variance based on terrain slope, making its utility very situational. The ability to pick up and toss Grenade Eggs created using Rear Egg in a similar manner to items in Smash also appears to be based off of the fact that eggs fired from Kazooie's rear end in Banjo-Kazooie can be picked up again by simply walking into them before they break.
Banjo-Tooie introduces different types of eggs aside from the standard Blue Eggs; Grenade Eggs are the third egg type. They explode instead of simply breaking on impact or distance expiry, dealing high damage and destroying many sorts of objects, but also hurt Kazooie if they explode too close. Grenade Eggs can only be fired one at a time and are mandatory for defeating several enemies and bosses.
In other languages
- In Banjo-Kazooie, this move made a fart sound when being used; such sound effect is absent in Ultimate. However, if the move is used while an egg is already out, a faint "toot" sound can be heard from Kazooie.
- This move was not named in Banjo-Kazooie or Banjo-Tooie, being rolled into Egg Firing as one ability, and is not present in any other Banjo-Kazooie games. This makes Ultimate the first time this move has ever been given an official name. However, the animation has always been internally named "egg ass", which the Japanese version literally translates for its name.
