Troff 'n' Scoff

Troff 'N' Scoff is a location found in every world of Donkey Kong 64 except Hideout Helm. As the name suggests, it features Troff and Scoff, who act as the gatekeepers to fighting each world boss. To enter the location, the Kongs must enter a portal depicting a headshot of both characters.

Description
Troff 'N' Scoff takes place inside an enclosed, symmetrical room with a large door leading to the world boss. There are two platforms: Troff is standing on the left one and Scoff is standing on the right one. A Tag Barrel floats to the left of the entry portal. A large panel depicting Scoff's head is located directly south of the entrance. It is surrounded by five smaller panels that each depict an icon of a Kong's head (or a question mark if a Kong has not been rescued yet). The panels are optional as they display the total number of Bananas that each Kong has in the current world.

The large door is locked by a silver lock, which is out of Troff's reach. As a result, the Kongs must stand on a Banana Pad, where they must feed a certain number of Bananas to Scoff to increase his weight. The remaining number to feed him is displayed on the large boss door, and it decreases by a number for each Banana fed to him. After the Kong feeds all of their Bananas, Scoff belches and then jumps on his platform, which somehow elevates Troff's platform. If the door number says zero, Scoff becomes large enough to elevate Troff to the lock, allowing him to unlock it. By doing so, the boss door cycles between the head icons of the five Kongs before stopping on the one who must fight the boss. The door opens but only the depicted Kong can enter; if the other four Kongs attempt to enter, the door shuts on them.

After obtaining the Boss Key and defeating the boss, the Kongs exit back into the world from the Troff 'N' Scoff portal, which then vanishes.
