(FOX NEWS) -- The often-decadent Fantasy Fest is in full flair this weekend in Key West.

At Wednesday evening's family friendly Pet Masquerade, entrants included costumed dogs, cats and a tortoise carrying a plush rabbit themed "The Tortoise and the Hare," drawing inspiration from the fable of the same name.

The overall winner was Diana Benton of Titusville, Florida, who dressed her two cats as country artists Willie Nelson and Dolly Parton, subscribing to the festival's musical theme of "In Tune But Off Key."

Other highlights of the event include Friday afternoon's masquerade march and a parade with floats and flamboyantly costumed marching groups.
