Frantic Factory is the third world in Donkey Kong 64. It is a dangerous toy factory. Chunky Kong is held captive here. The area's boss is Mad Jack, the evil Jack-in-the-Box. Entry to this level requires 15 Golden Bananas.
This stage is notable for having an arcade machine with the original Donkey Kong game. Completing this game will award Donkey Kong with a Golden Banana and, later, the Nintendo Coin. This stage is also notable for its maze-like nature, giving it its name.
- Lobby- Where visitors to the factory first enter. It includes a large red circular rug and a time clock where employees punch in. On the same floor, in a separate room accessible from Testing, is Snide's Hideout.
- Production- A floor below the lobby (and also below ground) is the Production floor. This floor includes the huge Machine, or Tower, where the music changes. The rest of this floor includes Candy's shop and Cranky's lab, plus the electrical house, which controls the machine.
- Testing- The testing floor, near the top of the factory, is a very tall room filled with giant toy blocks. Diddy Kong can Simian Spring to the top of these blocks, where there are windows all around. The moon can be seen from these windows. Funky's shop is on this floor, along with a 16-number puzzle for DK, a dart game for Tiny and a window where the Arcade room can be seen on the same floor.
- R&D- A research and development area at the top of the factory, surrounding the upper areas of the Testing room. It is a large area with many rooms where the Kongs each face a challenge. For example, Lanky faces a "Simian Says" game where he has to copy burping Kremlings by playing a six-note colored piano. Tiny has her first race with the Kremling car in this level. Small pits with metal grates circle the area. Also, there is a pit without a pole (which is the only area without where it can be found in closest to the R&D area's Kasplat) that leads to the storage room where a Kong will land on the steel platform.
