"Funny" reason I can think of: I suppose one of the reasons would be the sheer irony of a skunk smelling good.

Less funny reason: What the others have said.

Not funny at all-reason: There's this cartoon (I only know its Swedish name though...) which takes place on the Arc, had it been filled with talking cartoon animals and handled by a married bickering pair. One of the characters is a skunk, and the poor guy/girl (I really can't tell) is friendless and even lives on a separate little boat that is dragged behind the main ship.

Sorry for going off-topic, but what I'm trying to say is that Petunia perhaps is trying to smell good so she won't get bullied.
