To start this quest you should talk to Mabel and Geraldine (Pet Pal talent required).
We came across a pair of cows that were in fact two people who were polymorphed and enslaved by a witch. They want to be turned back into their human form.
Warning: This is timed quest. If you take too long to complete it, the cows will disappear and the quest will close.

Kill Corpse of Alice Alisceon (lvl 15).
The witch, Alice Alisceon, is dead.

4. Witch Outside
The witch's house is wrecked and empty.

The cows mentioned something about rats. It might be worth looking into.

7. Kept Potion
We decided to keep the potion for ourselves.
8. Drank Potion
One of us drank the potion and was transformed into a cow.
9. Has Witch Ingredient
