For this year's halloween quest you need to make 3 candies to get the Halloween kitty ear hat, then there is a hidden "secret" mission to get a Halloween mount.

To make the candy you need to get the ingredients, but you are only told one of the three ingredients, you're meant to talk to your friends to find out what the other two are. Well...to save those of you who are like me, who don't have people you can just ask, I've listed the ingredients needed to make the candies. The first three I can confirm work because I was asked those, the rest are what I've found online or over chat so please forgive me if any of them are wrong, if so please mention it for those working on this quest.

[Mint Chocolate Candy] *can confirm
1. Magic Powder (Green) - this is obtained via herbalism but if you don't have herbing, I'm sure there will be some on AH.
2. Peppermint Flower - again obtained via herbalism.
3. Chocolate - You buy this from a merchant, I got mine at Orbis merchant.

[Skull Candy] *can confirm
1. Skull Shoulder Pad - dropped from Dark Cornian in Leafre

Ok... so once you make 3 candies you get your kitty ear hat.

Now for the hidden mission (there is no quest prompt for this part) put that halloween kitty ear hat on and head over to Kerning City, head to Naora Hospital and while wearing the hat speak to Jane Doe. They will be all 'halloween already?', something like that and at the end of the interaction will give you a choice of the pumpkin mount or ghost mount.
