Golden Banana duping in Jungle Japes | Donkey Kong 64 Glitch

Found by Adam Whitmore
Definitely not one of the easiest or fastest of methods for GB duping. However, it is one of the more unique methods compared to the others.

By taking a rock out of Chunky Underground in Japes (if the GB rock and the entrance to the underground are open), the game assumes you are holding the rock with the Golden Banana inside. So, by bringing the rock in the far area of the map into the underground (by skew levitation:    • Skew Levitation | Donkey Kong 64 Glitch   ), we can clone Golden Bananas.

If you grab the GBs instantly, you lose the ability to due the Rock GB further. However, after breaking the rock to reveal the 25th Golden Banana, you get a GB which is unflagged and is not tied to any kong. Which means that you can continually dupe Golden Bananas and give them to any kong to fill the counters for Jungle Japes.

It should be noted that whilst you can collect as many golden bananas as you like (up to 400GBs per kong per level), the game will only save up to 7GBs per kong per level (If you collect 9GBs, you'll only have 1 upon reloading. If you collect 10, you'll only have 2. If you collect 16, you won't have any etc.)
