"This one is a bit tougher. Mainly because the little birds peck you and slow you down while the other ones dash through you and you cant really block them. You'll mainly want to be using the rifle and when you get attacked by the little birds give them a quick burst with the bellows, it'll slow them down and cause them to take burn damage. Also when the shard crystal drops give it a puff with the bellows and finish it off with the rifle for extra hp. Also I messed up versus the stink eyes, don't get yourself in a corner like that, circle the map and get them grouped up so some wont blow up on you while you try to take others out.
Volatile Fuel (flames spread wider)
Napalm Reservoir (flames cause lasting burn)
Modified Intake (flames cripple foes)

Streamlined Furnace (move faster while attacking)
