Mad Jack DK64 3D print model

Mad Jack is the third boss in the game Donkey Kong 64. Tiny Kong fights him in Frantic Factory, the third level of the game.

Some trivias:Mad Jack was originally going to be made entirely out of junk, being called Junk in the Box. His rusted springs show that he could be old, or he was made from scraps, supporting this.Mad Jack is the only boss that Wrinkly Kong specifies instead of the location of a Golden Banana. When a Kong approaches Tiny's door at the antechamber of Frantic Factory, Wrinkly says, Cranky can help Tiny beat the giant springy box. Even though a crash can be heard when he falls, his remains are nowhere to be seen at the end of the boss fight.Mad Jack's body appears to be larger than his box.Mad Jack is the only boss besides King Kut Out that does not do shockwaves.Like Puftoss, it is possible that he was just defending his territory, as the only evidence given in game that he is K. Rool's minion is the fact that he holds one of the keys to K. Lumsy's cage, which he must have gotten from K. Rool.-However, this theory can be disproven by the fact that he falls out of reject chute, presumably because he was too dangerous, which leads to assumption he was attacking Tiny due to nothing more but a desire to hurt or kill her.Even though he's made out of metal, his hair still parts before shooting his laser.During the battle, a high-pitched, menacing laugh will appear, but it is not made by Mad Jack himself, but rather is part of the music track. Mad Jack's real voice, as well as the aforementioned laugh, were taken from stock tracks recorded by the late Clarence Nash, the original voice of Donald Duck.In the Prima strategy guide for Donkey Kong 64, his name is incorrectly listed as Quack-in-the-Box. However, because Donald Duck's voice actor played Mad Jack, it's entirely possible the misnaming could have been an intentional joke.Furthermore, Mad Jack himself slightly resembles Donald Duck upon closer inspection, specifically his nose and mouth resembling Donald's beak.There is also a version of Mad Jack's boss battle soundtrack without his evil laughter.Though clearly made of metal, Mad Jack seems to possess magical abilities, as seen when he throws fireballs and turns himself invisible. There is a match to the high-pitched, menacing laugh with the distinguished-named scientist named Mad Jack that matches the same as the original Donkey Kong 64 Mad Jack. Mad Jack the Evil Scientist appears in an educational video game Schoolhouse Rock! as the second boss; however, Mad Jack the Evil Scientist does that laugh louder than the music's laugh.Turning the third Boss Key opens no new areas in DK Isles, meaning that a player can progress through the game and enter Hideout Helm without defeating Mad Jack. However, they must defeat him to reach the final battle against King Krusha K. Rool.
