Kick it, Bunny!

This chest is hidden under a waterfall that is on the river that runs through the largest island on the right side of the map. If you follow the river from left to right you'll see it at the top of the waterfall just on a ledge under the very top of the small waterfall around halfway down the river.

You'll know it's the right one as you'll obviously unlock the achievement, and this chest turns your bunny multi-coloured.
