Donkey Kong and Diddy Kong are on a quest to retrieve the former's banana horde from the Kremlings. They are doing it as quickly as possible, without bothering to enter all the bonus rooms.
Except this time, they've found a way to get the banana horde back without leaving the comfort of their own home. By using an ACE setup to inject code that triggers the ending cut-scene with Cranky Kong, they get the horde back in just over a minute. Please read the author's comments for more details.
