Ok I was thinking instead of boring ol' fighting there would be twists. The forest creatures could have effects on you, here are a few examples:
You have encountered Kakashi with lunges at you with Copy Wheel Sharingan!
Kakashi's sharingan would copy you and deal the same damage you do. If you have less HP than him, you die, etc.
You have encountered Sasuke which lunges at you with Curse Seal!
Sasuke's curse seal would give him strength, but hurt him during the battle: The curse seal hurts Sasuke for __ points of damage!
And many other things, but only if Neji can think of them.
