Glimmer's Galleon
In a secret room that's above the entry point. Go forward to collect
Glimmer, then backtrack to the entry point and head upwards. In
the same room where the first Kremkoin level is found pass through
the wall above the bonus area entry, into a room with a big "3"
of bananas. Pass through the ceiling of this room into the room
with the DK coin.
Open door above the entry point. Head upwards from the entry and
then follow the trail of bananas.
There is an opening on the bottom of the level, below and a few
screens left of the [G]. In a room that the passage leads to,
there is an open door.
