Character mistake: In the cutscene that happens when entering Jungle Japes for the first time, Donkey Kong struggles to get the first golden banana, then slams the ground to make it fall. King K. Rool describes this banana as "his first golden banana", but this is not how DK got the first golden banana, as the player picked it up after K. Lumsy opened the way to Jungle Japes.
