What is the bell rock island? Is there just one rock with money in it or more?
Basically it's one where there's a large pond with a small island in the center. You can't jump to it and you can't pole vault to it except in one spot.
In the one spot that extends far enough there's a rock you hit and break after eating fruit. Then you pole vault to the island where 5 rocks are and they all will be bells.
I get about 100k from it all.
