When your in the place with the big water fall ( troll hole ) theres a water fall go on the vine and jump threw it.
But keep going up the green slimy thing jump up it then.
Look around you might see a platform with the key ( platform is the thing that hold it ) you might also see the two coconuts there ( brown things with blue in midle ).
Don't smash them jump on them then jumo on the platform now go to the troll cave ( where ever that is I am stuck there too ) there you go you got the key.
