In a forest/jungle arena, Katniss defends herself with her bow and arrow in a shallow pond.
This scene was mostly inspired by the monkey attack scene in "Catching Fire", hence the pond.
Her two attackers - one of whom she has already shot.
Some of the trees.
A (slightly blurry, sorry) closeup of Katniss in the water.
The whole build.
And a final look at the scene.
