So, I've actually been brewing on ideas like this since Spring, but with how Summer was set up it really set a plan rolling in my head.

So how about for fall we have a Graveyard And Spooky Forest Seeking? Kinda like the Beach Seeking only with a graveyard and forest? We could have search items like Rakes and Shovels, you know, rake away of leaves or dig holes in the ground. And there could be lucky spots such as leaf piles, gravestones, hands coming out of the ground, maybe a black cat (Irony).
*Half the Seeking Map being a Graveyard, Other Half Being Forest
*Rakes to use in the forest to uncover objects
*Shovels to use in the graveyard to dig up objects
*Gravestones and Hands in the ground for Graveyard Lucky Spots
*Leaf Piles and Black Cats for Forest Lucky Spots

And instead of body parts, we could dig up or uncover other items to brew together pets kinda like potion items. Vampire Fangs, Werewolf Hair, Toadstools (There are ALOT of pretty mushrooms out there), Bat Wings, things like that to tell us the different types of pets.

And I was also thinking of Cauldrons to tell the Vis amount, (Poor Cauldron, Good Cauldron, Mystical Cauldron), and maybe candy and slime for base ingredients (Like the Water and Clay).
*Witch's Cauldrons for Vis amount
*Candy and Slime for base everything-uses ingredients

If anyone has pet suggestions (With item suggestions to stick in a cauldron), I'll be happy to record them.

Pet Ideas:
Witch's Familiar Lighira (Perhaps a ghostly cat for the item) [Me]
Bat Nytekrie (Types vary, but obviously Bat Wings for the item) [Me]
Werewolf Lupora (Werewolf Hair/Claws) [Me]
Dragon Fire Nephini (Dragon Scales) [Me]
Toadstool Zolnixi (Toadstools) [Me]

I like the theme you have going on, but I personally was hoping to have a slightly different way of achieving pets than a seeking-like thing again.

I would agree with Tap - I like the idea in essence but perhaps for next year when it would be something different? Rehashing the exact same setup with different images wouldn't drum up the same level of excitement we've come to expect from the Fall Fest I don't think.
