Launching in a somewhat disturbing and ominous manner, there's a combination of what might be considered 'jungle drums' along with dark chords, and other rather threatening sounds. Sticks bang together amidst unsettling chords and the odd grunt.
Even the birds sound rather perturbed and one hopes that the frog did not grunt like that because some careless combatant trod on him!
Overall it's a bit jumbled, but for those who have ever fought in a forest (perhaps in a LARP or a military exercise) it does make a kind of sense. This might be a good one to spook your players wherever they get ambushed, forest or not.
