1. Jackal (Anubian)
Or in terms of real world species, a melanistic African wolf.TF catalyst: What better than to be rewarded for your oh so gratuitous check-in on the dead that definitely wasn't an exercise in grave robbery on foreign land, than to touch a cursed amulet and be made into a guardian of them?
2. Fennec fox
Also known as the fenk.TF catalyst: Being naturally small (read: the smallest canid) and therefore primo shortstack material, consider: being literally squished down into one.
3. Gray wolf
Decidedly person-sized.TF catalyst: Assimilation by wolf cuddle pile. Whole pack of wolves nuzzling, licking and gently homphing a hapless human or what have you that happens to run into them, another wolf comes out.
4. Coyote
Also once known as the American jackal. Decidedly more chaotic than its African and Eurasian counterparts.TF catalyst: Cursed bag of Doritos. You are what you eat. It's triangles all the way down.
5. Red fox
The fluffiest of the list.TF catalyst: A curious new conditioner that promises luscious locks the entire animal kingdom would be jealous of. Delivers exactly as promised - right before the fluff starts to grow out. <3
Alternate for the Red fox TF:
You find a jewel and decide to pocket it. The next morning you wake up and find yourself a fox with a stack of letters and addresses to deliver them too.
