After you fought and beat the pumpKING, you moved on to the next night. Seems like a grim reaper appeared. Watch out for his attacks since he can be very dangerous. One notable thing about him is that every damage he does, he heals back some health. 1 damage to you = 10 health to him. Try to not get damaged throughout the battle! (Also every powerup except cure has been now gotten rarer due to the grim reaper snatching them. The cures are more common because the grim reaper wants you to get them so he can steal more health.)
