|Extra 10 is insane near the end.. I watched the walkthrough video of it just to see how they did it, and was able to beat it after a few more attempts of getting there.|
Extra 11 isn't nearly as bad as 11. It's hard, but in a fun way. It involves stuff you've done before in other stages, plus there's rising lava.
But that still isn't 100%.. I still haven't gotten the C rank in the endless banana grab minigame. I decided to give that another shot.. it's actually not that bad if you're focused, and I realized it's easier to get the timing down if you let the banana fall completely below DK's hand before grabbing it
So yeah, that's 100%. The only other thing is staff speedrun times, that can be unlocked by getting AAA scores on all the minigames.. screw that noise.
