The Final Battle
Upon Gruntilda's near defeat by Banjo and Kazooie, she summons a magical force field to deflect all remaining attacks. During this time, four statues of Jinjos appear from each corner of the battlefield, standing upon a pedestal with a hole. Once firing approximately three eggs into the pedestal's hole, the Jinjo statue will awaken, revealing a colored Jinjo. At this time, the four Jinjos are Purple, Yellow, Green and Orange.
Once awakened, the Jinjo will fly into Gruntilda, damaging her. As all four Jinjos are awakened and attack Gruntilda, one final large Jinjo statue will arise from the ground. He calls himself "The Mighty Jinjonator" requesting you activate him. Being substantially larger than the previous Jinjo Statues, the pedestal on which he stands is characterized with four holes which you need to shoot six eggs in each hole to activate, and since Gruntilda's attacks always go right through the Jinjonator, and she is always attacking, the Jinjonator is very hard to activate.
Once activated, a giant Blue Jinjo with glowing red eyes will emerge from the statue. Each of the varied colors of Jinjo (purple, orange, green and yellow, respectively) will fly into the giant Blue Jinjo, absorbing them on impact. The Mighty Jinjonator will proceed to circle around Banjo like a normal Jinjo before ramming into Gruntilda multiple times. As she is struck, explosions of the Jinjo colors will erupt on impact with Gruntilda. The Mighty Jinjonator continues to pound into Gruntilda while she claims her strength will allow her to withstand the Jinjonator's attacks.
As the battery continues, The Mighty Jinjonator will stop before the witch and bellow one final word: "Jinjo". Gruntilda now shows fear towards him. As the word is said, The Mighty Jinjonator finishes the assault with one final smash into the now helpless Gruntilda.
As she falls from the tower, she casts one final spell at Banjo, which misses. She lands at the base of Spiral Mountain, her impact creating a hole which is sealed by a boulder fallen from the castle's peak. Gruntilda attempts to move the rock and escape, and summons Klungo to her aid. He attempts to move the rock, unsuccessfully, until the start of Banjo-Tooie.
