Kannon's Klaim
It's at the bottom, extreme right, of the first Kremkoin bonus
area (below). You will have to use Dixie's helicopter jump to
get the DK coin.
It's at the bottom of the level, directly to the right of the
entry. Walk across the entry platform and use Dixie's helicopter
jump to the right when the platform ends.
There is a bonus barrel to the right of the second platform after
the continue barrel.
Just below and left of the end target. Fall down between the target's
platform and the platform immediately to its left; fall slightly
(1-2 monkey-widths) to the left. It's easier to land on if you
use Dixie's helicopter spin to float downwards slowly.
