An animated Wallpaper gif of Oleander in a witch/sorceress/enchantress costume with a cauldron and spirits flying out of of it one of the spirits is Fred and then he eventually turns into his physical form. After that the cauldron truns to another sinister colour with more deomonic spirits come out of the cauldron as more dark magic is being used for spells.
There could be a trick or treat version of this where Pom opens her bag of goodies from Halloween and Fred pops out the bag and scares Pom and her dogs.
Watch out for Killer Clown Cows tonight. " They're coming to get you".
