"To fight this disease and all who have been infected by it, I have prepared some high-tech, state-of-the-art weaponry that will cure everyone that has been infected." said Doctor Whooves confidently.

"Here", said Doctor Whooves to Derpy. "This will help us fight the infected ponies. We will not hurt them, but only cure them, so they can go back to living their normal lives."

"Let's suit up!", said Derpy excitedly.

"Hm.. yes, indeed", said Doctor Whooves.

The two of them put on their high-tech armored suits and walked out of the secret room. Doctor Whooves closed it and re-entered the secret passcode. Then the doctor and his assistant walked out of Doctor Whooves' house, and out into the infected area. Except there was one problem.

"Bloody hell..." said Doctor Whooves nervously. "We're vastly outnumbered!".
