Gobbler, the Turkey Warbeast!
I decided to craft his rules as a character Shredder (although I guess he could be a character Harrier too), as I figured it was most appropriate for a crazy Turkey. It might seem a bit overpowered but I decided to give him the animus Gobble Gobble! which gives him Rabid. It's twice as expensive as for a Shredder, since it will be really good for a Legion warlock to put on themselves. I figured that a fairly fragile warbeast with such a great animus wouldn't be so overpowered, as Gobbler will likely die pretty easily with any concerted attacks since he also lost snacking.
In the end, though, I thought it would be hilarious to imagine a giant turkey going "GOBBLE GOBBLE!" and going crazy flying at your opponent! Enjoy and have a happy Turkey Day!
