Wily 4
Final Stage

Corridor
The approach corridor is full of worm enemies, Most of them are spaced two slides apart, except the third one which is a jerk. 
 Dr. Wily can only be damaged by Pharaoh (good damage) and Ring (1 HP per shot), so farming these worms for ammo may be your only way to finish the game. A WR attempt should not need any additional ammo here, but in a race scenario, a bad Ring refight or some other scenario may result in needing ammo.
