Beaver Village is either a side level or part of the story it's hard to tell. You get to it from from Croc Swamp, once that is finished - Across some logs from where you start the croc level.
You have to complete a flow system taking water round the level - by raising the missing parts of the wooden structure.
1) In the left as you enter, use Gorzan to punch the button to drop a lever. Use the lever to get a chest, open it to build a crank. This lowers one part of the wooden structure.
2) To the right of the start point use a Lion and roar to break a wall, then wall jump up to the top. Push off a movable box to get a chest brought up. Make is then open the chi door and turn lever activate wooden structure two.
3)To the far right, use the rope to walk over to a dig spot. Dig up parts to build lever and raise a platform. Jump over to the left and pick up handle, then go back to the rope walk. Add the crank in position and turn lever for the final wooden section.
The trophy will pop.
