Donkey Kong 64/Trivia

Genre Killer: Collectathons released after this game were considerably toned down in the amount of collectables.
Hey, It's That Voice!: Donkey Kong is Mumbo Jumbo.
Name's the Same: DK64 level "Crystal Caves" shares a name with a song in Super Mario World 2. That plays in cave levels.
Urban Legend of Zelda: Several, the most notable being an inaccessible room in Creepy Castle with a glass wall. If you stand on the hallway outside of it and use a first-person perspective, you can see a tall, carved stone pillar with a Monkeyport (teleportation) pad for Tiny nearby as well as a purple banana balloon floating over it. The room appears to be useless. King K. Rool's control room also features five steel kegs with the Kongs' faces painted on them. Probably nothing more than a little detail, but it sparked some speculation back in the day.
- Until people learned how to get to the room. The Monkey Port pad is in the Stock Car Race room across the hall, behind the Frantic Factory model. In order to get into that room, you need to get Tiny into the ballroom. All Tiny has to do to get in there is have Diddy open the door and switch characters before it closes.
  - Then people began to question why a room that required that much effort to get to was empty, which lead to more rumors.
- The fact that this was the first Donkey Kong game since Donkey Kong Country not to feature a Lost World sparked a lot of urban legends back in the day.
