Fear of Foul Odours (Osmophobia)

A disgusting smell invades Figaro's house. Figaro tries to fight it but the stench proves hard to evict until Figaro discovers that it is emanating from his gardener, Boris.
Figaro lures Boris inside and puts him through a cleaning machine. This separates Boris from his odour, resulting in a sweet-smelling gardener. The foul odour however escapes, taking on a life of its own!
The personified Foul Odour begins pursuing Figaro through the house. How will our fearful hero escape from this smelly monster?
