Fear of Disease (Pathophobia)

After being sneezed on by a snotty bird Figaro catches a horrid disease.
Luckily a passing 'Snake Oil Salesman' arrives with the cure!
It seems to work, but his miracle potion doesn't come cheap. When Figaro runs out of money, the only things he has left to exchange for the wonder drug is his house.
The salesman has made the deal of his life, but will his own dastardly scheme get the better of him?
